Sammy Sosa swings at a 0.15kg baseball and accelerates it at a rate of 3.0 x10^4 m/s^2. How much force does Sosa exert on the ball? F=ma (30000m/s^2)(0.15kg) = 4500 N Can someone make sense out of these problems? How is it accelerating at that rate? I've seen car crashing problems not...

Homework Statement Baseball -force and impulse- question A pitcher throws a baseball to a catcher in a straight line, like any ordinary pitch. Assuming that the ball arrives to the catcher at the same speed as the pitch is thrown, which player ends up attaining a larger force, the...

Homework Statement A baseball is hit at ground level. The ball is observed to reach its maximum height above ground level 3.0 s after begin hit. And 2.5 s after reaching this maximum height, the ball is observed to barely clear a fence that is 320 ft from where it was hit. How high is the...

Homework Statement A major league pitcher can throw a baseball in excess of 42.4 m/s. if a ball is thrown horizontally at this speed, how much will it drop by the time it reaches the catcher who is 15.3 m away from the point of release? Homework Equations v=d/t and...

A second baseman tosses the ball to the first baseman, who catches it at the same level from which it was thrown. The throw is made with an initial speed of 21.0 m/s at an angle of 35.0° above the horizontal. (Neglect air resistance.) (a) What is the horizontal component of the ball's velocity...

A baseball leaves a pitcher's hand horizontally at a speed of 165 km/h. The distance to the batter is 18.3 m. Neglect air resistance. (a) How long does it take for the ball to travel the first half of that distance? s (b) How long does it take for the ball to travel the second half of that...

A baseball has mass 0.145 kg. A. If the velocity of a pitched ball has a magnitude of 45.0 m/s and the battered ball's velocity is 55.0 m/s in the opposite direction, find the magnitude of the change in momentum of the ball. delta p = m*delta v = m*(v2 -v1) = .145 kg (-55.0 m/s - 45.0...

A 0.14 kg baseball moves toward home plate with a velocity vi = (-37 m/s) x. After striking the bat, the ball moves vertically upward with a velocity vf = (13 m/s) y. Find the direction and magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for...

A major league pitcher can throw a baseball in excess of 42.0 m/s. if a ball is thrown horizontally at this speed, how much will it drop by the time it reaches the catcher who is 15.1 m away from the point of release? I worked this out as an x and y problem and I got 2.57 for the distance at...

Eh, this is sort of a simple question. Milt Famey hits a line drive to center field. As he rounds second base, he heads directly for third base, running at 20 ft per second. Write an equation expressing.. blah blah blah. I'm not asking to do the mathematical part. I just don't know...

A pitcher throws a 0.145-kg baseball, and it approaches the bat at a speed of 53.6 m/s. The bat does Wnc = 77.4 J of work on the ball in hitting it. Ignoring the air resistance, determine the speed of the ball after the ball leaves the bat and is 28.5 m above the point of impact. The only...

A baseball pitcher throws a ball straight up into the air at a speed of 21.0 m/s. In the process, he moves his hand through a distance of 1.40 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed. My problem is that I don't know where to use...

An autographed baseball rolls off a 1.2m high desk & strikes the floor 0.37m away from the desk. The acceleration of gravity is 9.81m/s^2. How fast was it rolling on the desk before it fell off?

a baseball thrown from rest, leaves a pitcher's hand at v1 m/s. If the average force exerted by the pitcher is doubled, all else remained the same, with what speed will the ball leave the pitcher's hand given v1. just looking for some direction, I haven't done problems like this in a long...

Alright, I am really stumped. Was wondering if somebody could point me in the right direction, because I am lost. "The fastest recorded pitch in Major League Baseball, thrown by Nolan Ryan in 1974, was clocked at 100.8mph (45.06163m/s). If a pitch were thrown horizontally with this...

If a baseball player throws a ball a horizontal distance of 100 m at 30degrees latitude in 4s, by how much is it deflected laterally as a result of the rotation of the earth? Well I think i use the equation f = -2Ω u sinΦ where Ω is 7.29x10-5 but i am not sure where all of the...

A baseball hit at an angle of a to the horizontal with initial velocity v0 has horizontal range, R, given by R = (v02 / g)sin(2a) Here g is the acceleration due to gravity. Sketch R as a function of a for 0 < a < pi/2. What angle gives the maximum range? What is the maximum range...

Hey. I did some calculations, and estimated that an average person hitting a ball with a baseball bat would apply approximately 600-800N to the ball. Does this sound approximately right, or am i way off?

Hey. For my physics class, we are required to do whatever it takes to calculate the force one can apply with the swing of a baseball bat. We are given a ticker timer, a stopwatch and a meter ruler (to simulate a baseball bat). We can use other things if we wish, such as an actual baseball bat...

Hi all. I have a problem that states - It's the bottom of the ninth with two outs and the winning runs on base. You hit a knee-high fastball that just clears the leaping third baseman's glove. He is standing 24 m from you and his glove reaches to 3.1 m above the ground. The flight time to...

so in the world series youve got two teams and the series ends when one team wins its fourth game the teams are say equally likely to win anyone game what is the probability that the series will last exactly four games? five games? six games? seven games? if i know 4 i could figure out 5 6...

I have a rather simple question for the minds who paruse this forum. My question is this. Can a baseball thrown overhand by a human being by provided with enough backspin for it to escape it's initial velocity vector, and in fact actually rise as it approaches the plate?Thank you,Tim.

Can someone check if i did these two questions right please? The questions are: 1. A baseball diamond is a perfect square with each side measuring 90 feet in length. A player runs from the first base to second base at a speed of 25 ft/s. How fast is she moving from home plate when she is...

For a question on one of my assignments, we have to explain how a curveball works. I have been reading a lot on the internet on it, but he says that we do not need the magnus effect to explain it (which all the sites weem to use). Also, he said for bonus we could explain how it is...

Cuba's uniforms are very red. But are they red enough to throw off the Dominicans? I am cheering for DR for no real reason. Who do you think will win? Japan vs. Korea tonight. I like Japan. Again, no real reason. Call it women's intuition. (:rolleyes:) P.S. I am learning about baseball...

i have to do this project where i have to compare and contrast a Baseball helmet and a Rock climbing helmet and describe how each is appropriately designed to its use. - have to make reference to each of Sir Isaac Newtons 3 laws - describe how force is minimized - describe several features of...

I just walked out of the optomersit, my eyes sigfincantly worse than when I went in.. He used three kinds of eye drop, one yellow and two claer, than he pointed a C02 laser at my retina (that's what it looked like to me). I think one of them silated my pupils, or the opposite, or something...

ok can someone please explain to me why this is wrong? debroglie of a baseball weighing 1kg is h/(1kg * v). You through this at a double slit at 10^-34 m/s which makes the wavelength equal to 6.63 meters. for a double slit its d*sin(theta) = m * (wavelength) so you get theta = sin^-1(6.63/d)...

This is a simple problem, but for some reason i can't come up wit the answer. I am i using the wrong formula? A base ball is traveling and strikes a catchers mitt, bringing it to rest. the mitt recoils 11 cm. m=.14 kg vi=45 m/s vf=0 m/s d=11cm (.11 m) i used the formula vf^2=vi^2+2ad to...

Hey, There is a question in my textbook that I don't understand the answer too. THey show a diagram of a baseball bat and say if the baseball bad it cut at the location of its center of mass, do the two pieces have the same mass? They say no, the piece with the handle will have less mass than...

i cannot get the question since i don't know how to play baseball... this is the question... The manager of a baseball team has picked the nine players for the starting lineup. In how many ways can he set the batting order so that the pitcher bats last? im just guessing, is this correct...

I couldn't get my head around this problem... I'd like some input and some answers to aim towards please... I'm actually a pretty bright student, I just can't figure this out... maybe a blonde day lol? :smile: A baseball of mass 55g leaves the pitchers hand at a speed of 48m/s. THe...

someone posted an interesting problem from another board. now, the upcoming world series have chicago playing & they haven't won it since 1918. last year's winner, boston, hadn't won since 1917 ! the problem posed was: "what are the odds of two teams (not specifically having to be...

A pitcher throws a 0.126-kg baseball, and it approaches the bat at a speed of 32.6 m/s. The bat does 71.7 J of work on the ball in hitting it. Ignoring air resistance, determine the speed of the ball after the ball leaves the bat and is 29.6 m above the point of impact. i found that the...

Two full games for the price of one. (go 'stros) My prediction: Cards over ChiSox in the WS.

Hey, have stared at this problem for a good half hour now, and my brain must be completely shot by now so I am having difficulty solving. If anyone can point me in the right direction, I would greatly appreciate it. Thanks! When Babe Ruth hit a homer over the 12m-high right field fence 95m...

during a baseball game, a batter hits a popup to a fielder a distance of D m aways. the acceleration of gravity is 9.8m/s^2. if the ball reamins in the air for T seconds, how high does it rise. 1. h=D/4T 2.h=1/8gT^2 3.h=4D/T 4.h=2D/T 5.h=D/T 6.h=2gT^3 7.h=D/(2T)

Just watched some of the John Roberts hearing. Made simplistic analogy of the proposed position being like the umpire at a baseball game. To paraphrase: "to call balls and strikes and not to pitch or bat". Key points I heard from his speech: (which was basically a canned interview speech as...

A cardinal (Richmondena cardinalis) of mass 4.50×10−2 and a baseball of mass 0.140 have the same kinetic energy. What is the ratio of the cardinal's magnitude of momentum to the magnitude of the baseball's momentum? i derived an equation of 1*p^2/2m and I am not sure where to go from there.

Q.Ted Williams hits a baseball with an initial velocity of 120 miles per hour (176 ft/s) at an angle of q = 35 degrees to the horizontal. The ball is struck 3 feet above home plate. You watch as the ball goes over the outfield wall 420 feet away and lands in the bleachers. After you congratulate...

Why in world is this a congressional issue? Sure, there appears to be a problem, and the situation may need to be addressed, but isn't this an issue for law enforcement, and not the leaders of a nation. Considering all of the problems that the US faces, I would think that ball games should...

[FONT=Arial]I need help with this question as well: If the baseball in example 4.5 is caught by a person whose hand recoils 0.30 m, calculate the average force on the person's hand. (The initial speed of the baseball is 44.7 m/sec and its mass is 0.50 kg.) This is what i have, but I'm not sure...

Hi I have a question A baseball player hits a baseball that lands in stands 24 meters above the playing field.The ball land with velocity of 50 meters per second at angle of 35 degree below the horizontal. a.If a player hits the ball 1 meter above the playing field,what was the velocity of...

The center of mass of a pitched base ball (radius=3.8cm) moves at 38m/s. The ball spins about an axis through its center of mass with an angular speed of 125 rad/s. Calculate the ratio of the rotational energy to the translational kinetic energy. Treat the ball as a uniform sphere...

There was a heated argument at my workplace today on what could drive a golf ball farther, a baseball bat or a golf club. Is it mass x velocity = force...end of story... or is there more to it? I think we are going to have to take an aluminium bat and some golf balls to a driving range to settle...

Hi. I need some help. A baseball diamond is a 90 foot square. A player approaches 3rd base at a rate of 28 feet per second at the instant he is 30 feet from 3rd base. Find the rate of change of the player's distance from homeplate. So df/dt= 28 But I don't know where to go from here.

Please help me with this question An outfielder catches a baseball of mass .14kg moving at 50m/s. The glove and ball move .50m during the time the ball is stopped. What is the average force exerted by the ball on the outfielder's glove? At first I thought this questin had to do with F=ma...

My Baseball coach is also my physics instructor. He says that "it is easier to throw a baseball horizontally than it is vertically" -- and that throwing speed varies with elevation angle approximately as: v_0cos(\frac {\theta}{2}) \text{ m/s} \text {where }v_0 = \text{the initial velocity...
