I have a problem that I can't figure out what formula to use. It states: In a football game a kicker attempts a field goal. The ball remains in contact with the kicker's foot for 0.0588 s, during which time it experiences an acceleration of 290 m/s2. The ball is launched at an angle of 48.5 °...

A golfer gives a ball a maximum initial speed of 28.5 m/s. (Neglect air resistance.) (a) What is the longest possible hole in one for this golfer? Neglect any distance the ball might roll on the green, and assume that the tee and the green are at the same level. m (b) What is the minimum speed...

I have a problem that I'm having trouble with. The question is, A farris wheel that has a radius of 5 meters, takes 32 seconds to complete one revolution. (a) what is the average speed of the rider on the Ferris Wheel? (b) If passenger drops keys when at top of the wheel, where does it land...

I have a question... it may seem like a very basic one, but still I am not able to answer this. "Why all satellite launch pads are located on east coast"? I can understand why satellite neeeds to be launhed in eastward direction, but when I tried to correlate these two together, I was told...

I've pondered, why does The Shuttle use tiles for re-entry and not lauch. The tiles are used for landing cause the air friction is so high with the speed. Well when The Shuttle launches it's going at tremendous speed also. Going at many times the speed of sound it should cause friction with air...

Grr. This is still bugging me. Outlook Express insists on launching any links in Firefox rather than IE. I cannot find the switch to change this.

So the folks at NASA are thinking about testing a linear launch system. It would uses linear induction motors like rollercoasters are using now. The trakc would be about 5 miles long and eventually curve up I sure. Once at the end the space vehicle will have gained enough momentum to get into...

http://www.washingtonpost.com/wp-dyn/content/article/2006/03/04/AR2006030400860.html It's been two years why they just starting to lanuch a crimnal investegation? I don't watch football.But I'am kind of intersted to see what if it was propous what was the motive.

A student throws a ball with a speed of 15.0 m.s-1 at an angle of 40.0° above the horizontal directly toward a wall as shown below. The wall is 10.0 m from the release point of the ball. Now I did figure this out. The vertical component of velocity (initial) is v= v(inital) sin angle, and in...

Can anyone help with this problem?? Children bring their old pumpkins to a tower and compete for an accuracy in hitting a target on the ground. Suppose the tower height is h=8.0m and the bull's eye on the ground is a distance d=3.4 m from the launch point. (neglect air resistance.) If the...

The launching speed of a certain projectile is 5.2 times the speed it has at maximum height. What is the elevation angle at launching? Could someone just give me a starting point or a hint in the right direction? I know that the horizontal velocity doesn't decrease, and the vertical...

Anyone else watching the Launch of the Pluto probe? www.nasa.gov/multimedia/nasatv/index.html They've just filled the Helium and Oxygen tanks to flight levels and are performing tests on them. About T minus 35-40 minutes.

Deriving a Launch Angle Equation -- Projectile Motion -- Please Help This is physics in the area of projectile motion. My class and I are doing a lab where we have to calculate the launch angle in order to perform a successful lab. The experiment is as follows: the projectile launcher releases...

Yeah, they'll have those right after they have satellites that can scratch your ass with a laser beam from space. Cheers...

will space shuttle blow up again ? would be much better idea to send shuttle into the space on 4th of july, we have never enough of fireworks and stuff exploding.

I'm Currently Making A Water Rocket And I Want To Obtain More Information About The Factors That Might Affect It From Launching Higher. Thanks For Your Help Really Appreciate It.

Did I do this right? I'm relying on a formula the teacher gave us in class, without quite understanding it intuitively. So I'm just rewriting the formula to solve for my unknown and plugging in numbers. A sounding rocket launched from Earth’s surface is to achieve a final speed of 1000 m/s...

The answer that the book gives for the question: What is the launch speed of a projectile that rises above the Earth to an altitude equal to the Earth's radius? Ans. 7.91 km/s Now I have the question: What is the launch speed of a projectile that rises above the Earth to an altitude equal...

Is there something wrong with this reasoning: First the question: "A rocket A leave Earth at a speed v at a time where the clocks onboard and those on Earth read 0. After a time T (for the Earth's clock), a second rocket is lauched with a speed u > v. The second rocket catches up with the...

Launched today at 1:47 pm. Impactor will hit comet Tempel 1 on July 4. Love the real-time blog for the launch... http://www.space.com/missionlaunches/delta2_launch_050112.html

hi, I'm an undergraduate from the University of Newcastle Upon Tyne, and I'm trying to develop an accurate model of a launch of a saturn V rocket for a project. i have access to the technical specs like fuel capacities, consumption rates, etc. but i need help on some of the harder...

how to you find max velocity...average thrust..energy stored in engine...and time to max height... We did a real rocket launch, and i onli got the following information: 3.48s for rocket to reach max height..according to timer, distance from launch pad..99m, angle 33 degree. I need hints...

Does anybody know how to mathematically prove that an object launched at a 45 degree angle will have the largest possible displacement?

A ball is launched up a semicircular chute in such a way that at the top of the chute, just before it goes into free fall, the ball has a centripetal acceleration of magnitude 2g. 1.)How far from the bottom of the chute does the ball land? Your answer for the distance the ball travels from...

Does anyone know the formula to find launch speed?

Hello all. I am doing some research on the space shuttle for a class project, and I am having some problems with my data. I was hoping someone could show me the error of my ways. I got all of my data from this site: http://spaceflight1.nasa.gov/shuttle/reference/basics It says that 2...

A 0.015 lb. bullet leaves the 23 in. barrel of a 0.30 caliber rifle (whose bore diameter is 0.30 in) at 2000 ft/s. Find the average pressure of the gases in the rifle barrel while the bullet is being accelerated.

What do you do when you lose a Lander? Simple, launch another TWO! Huh? And why on Earth would anyone sponsor Beagle’s 3 and 4? Beagles 3 & 4 (on the way); http://www.guardian.co.uk/uk_news/story/0,3604,1223765,00.html An image (by ESA) of Beagle 3 Lander...

This is a new launch plaform idea to assist Nasa in meeting it's extra-planetary goals. It seems that a large helium-supported platform in the upper atmosphere could save a lot of launch energy and pollution. The platform might be quite large, perhaps 0.5 to 2 km in diameter, and could be...

Here is my problem, can anyone help me out? Prove the maximum range of a skier going down a ski jump is given by (theta) = 45degrees - phi/2 , where theta = optimal launch angle , phi = slope angle of take off with respect to the incline of the hill. I have the following equations to use...

Hey, can someone please help me with this? *restates question* I need 10 principles of physics applied to a space shuttle launch. Thanks!

My physics class project is to construct a catapult. My question is what is the optimum launch angle for distance. This was posted awhile back by someone else, but i can't find the post again. I think it said that because of air resistance an angle slightly above 45 degrees is optimum for...

Ok, this is a really stupid question, but it's just killing me for some reason. What do you call the person who leads a shuttle launch? I need help quickly!

if were posible to construct a maglev launch system on our moon how much energy would be required to launch shutle sized space craft?
