Would greatly appreciate an explanation on this question, not sure I even understand what they're asking.

Hi, Looking for Centrifugal force on water droplets on my spinning Basketball at 33 RPM, 45 RPM and 78 RPM

I was practicing basketball free throws at a local park today when a 35 y/o male crossed the courts near me and seemed to maybe be mumbling to himself, but I said a freindly howdy anyway. He responded with a similar greeting and asked if he could shoot hoops with me, and I replied that I mostly...

I enjoy playing basketball and I’m trying to figure out how to increase my range, so that I can shoot further. There are many contributing factors, but I’m curious how the movement of the ball and my arms contribute to how much power I can get behind the shot. This is difficult to explain in...

I have this backboard made of wood (gift). The board itself has 2 vertical wooden 2x4. I need to hang it on a palm tree. I've checked the measurements and the palm tree has a good 20 inches side to side (diameter). I've had 3 different ideas and Id like to get a better one. 1. Drill 2x10"...

Hello all, I remember a story from late 2014, when I watched a gameshow "Who is he/she?" This gameshow requires panel judges (often composed of celebrities) to guess which is the fake person with specific occupation (such as barber) out of three possible candidates present to them. In an...

I am no basketball expert. I have never watched an entire basketball game in my life. However, several times in my life I have watched a few minutes of basketball games here and there enough so that I am familiar with the basics of the rules and objectives of each team in the sport of...

Homework Statement You should shoot a basketball at the angle ##\theta## requiring minimum speed. Avoid line drives and rainbows. Shooting from (0, 0) with the basket at (a, b), minimize ##f(\theta)= 1/(a \sin (\theta) \cos (\theta) -b \cos^2 (\theta))##. (a) If b =0 you are level with the...

I was wondering how much I would have to charge a basket ball of mass M, so that I would begin to feel the inertia of the electrostatic field energy. We can calculate the total electrostatic field energy surrounding the charged basket ball, call it E. Can we then equate this energy E with a mass...

I've got a character who's from another planet who gets pulled into a pick-up game of three-on-three. No, seriously. So, how would a being who saw the game purely as physics in motion describe things like lining up shots and things like that? Just curious. Nothing elaborate. Just your common...

Homework Statement Ok, relatively simple question here, but I have a newb doubt... "A basketball player with a mass of 112kg can jump 0.92 m into the air during a slam dunk competition. Calculate the force that pulls the player back towards the floor." Homework Equations ## \vec f = m \vec...

Hi all, My understanding for why a basketball bounces is that the Earth acts against the ball, causing it to deform due to the ball having a downwards inertia and wanting to continue traveling down. This deformation reduces the volume inside the ball, in turn increasing the air pressure which...

Homework Statement A bascketball player , who has a weight of 890 N , jumps vertically with a height of 1.2 m , 1- Find his speed when he left the floor. 2- If the time that takes the basketball player to quit the floor is 0.3 s, what is his average acceleration ? (I don't understand this...

Homework Statement A basketball player throws the ball at a 60° angle above the horizontal to a hoop which is located a horizontal distance L = 2.8 m from the point of release and at a height h = 0.4 m above it. What is the required speed if the basketball is to reach the hoop? Homework...

Homework Statement trying to figure out how to calculate the angle of release needed to shoot a basketball in a rim. Here's the data I have so far: distance from shooter to rim: 6.28m height of rim: 3m height of shooter: 1.75m Initial velocity at time of release: 8.68 m/s ( hypotenuse of...

Were doing a project where we have to use Physics for derive an equation for the perfect basketball shot. Were still in the calculation phase and I've made a list of concepts to consider: Projectile motion ( ball to rim) Air resistance ( is this negligible? ) Velocity of shooter at apex of...

Hello all, I wasn't sure if this question should be placed here or on algebra forum, but it is related to probability, so I put it here. A basketball player shoots several times during some time period in a game, and scores less than 80% of his shots (let's say after the first quarter, but the...

1. What forces and impulse impact on a bouncing basketball? I understand that it is the gravitational force, when it falls, then the normal force when it is on the way back. Are there any additional powers? The momentum, I came to the potential energy = kinetic energy, where I got the speed...

Putting spin on the ball improves it’s stability (the spin imparts angular momentum and it takes an outside torque to change angular momentum), but at a cost. As you know, for a given input of energy, spin consumes some of that energy and leaves less for translation. Part A: So, How much more...

Homework Statement A 0.624kg basketball is thrown straight down and strikes the floor at a speed of 7.10m/s. The floor applies an average force of 67.2N for a duration 0.120s, causing the ball to bounce back upward. How high does it bounce? The Attempt at a Solution I'm not actually sure on...
