What is the velocity just before bouncing a ball with the floor from 1 meter altitude?...
. Let us examine a ball in the process of bouncing off of a floor. As we discussed briefly in class, if the ball has spin then this is a very complicated problem. So let us assume that the ball has no spin for the duration of the bounce. The ball hits the floor going vertically down. (a) Draw a motion diagram showing the motion of the center of mass of the ball during the bounce. We are only interested...
A basketball (m = 0.60 kg) is dropped from rest. Just before striking the floor, the ball has a momentum whose magnitude is 2.8 kg·m/s. At what height was the basketball dropped?
QUESTION 1 A ball of mass 5.0kg is lifted off the floor a distance of 1.7m. 1. What is the change in the gravitational potential energy of the ball? 2. Now you release the ball from rest, and it falls to the floor. What is the kinetic energy of the ball just before it hits the floor? 3. What is the velocity of ball just before it hits the floor? QUESTION 2 Suppose that the ball in the last question...
Alex bounced a 0.59 kg rubber ball off the floor. The ball's speed just before impacting the floor was 12 m/s, and the speed just after the impact was 4.5 m/s. What implies Ly was applied to the ball by the floor? If the ball was in contact with the flow for 0.036s, what was the magnitude of the average force applied by the floor on the ball? Find Impluse Find Average force
(a) A ball is dropped from rest from an initial height h above the floor. It then bounces several times. Draw graphs the position y(e), velocity v, (e) and acceleration ay () of the ball for two complete bounces (hitting the ground t for py Ct) ay (t) (b) If the ball is released from rest at a height h the ground? 1.50 m above the floor, how fast is the ball moving when it reach (c) If the ball...
A soft tennis ball is dropped onto a hard floor from a height of 1.55 m and rebounds to a height of 1.03 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. -Answer is 4.49 m/s (c) Calculate its acceleration during contact with the floor if that contact lasts 3.50 ms. (d) How much did the...
1) a)You are asked to find the initial velocity of a steel ball from a spring loaded launcher. You place the launcher on the edge of a table 1.0 meter above the floor and launch the projectile several times horizontally. If you find that the average distance the ball travels is 1.3 meters, what is the initial velocity of the ball? To solve a problem like this, use equations for the y-motion to find the time and then the x-motion...

A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.13 m. (Assume that the positive direction is upward.) (a) Calculate its velocity just before it strikes the floor, in m/s. (b) Calculate its velocity just after it leaves the floor on its way back up, in m/s. (c) Calculate its acceleration (in m/s^2) during contact with the floor if that contact lasts 3.50 ms. (d) How much...
A soft tennis ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.10 m. (Assume that the positive direction is upward. Indicate the direction of velocities and accelerations with the sign of your answer.) (a) Calculate its velocity (in m/s) just before it strikes the floor. (b) Calculate its velocity (in m/s) just after it leaves the floor on its way back up. (c) Calculate its acceleration (in m/s2) during...
