If The Ball Accelerates Uniformly When It Hits The Floor

A calculate its velocity just before it strikes the floor.

If the ball accelerates uniformly when it hits the floor.

A book is knocked off a bench and falls vertically to the floor. When dropped from a height of 2 5 monto a concrete surface a ball must rebound to a height of 1 4 m. A car initially traveling with a uniform velocity accelerates at a rate of 1 0 m s2 for a period of 12 seconds. During impact the ball compresses by approximately 6 mm.

When a tennis ball bounces from a racket the ball loses approximately 30 of its kinetic energy to thermal energy. How fast is the ball moving when it hits the concrete surface. A ball rolls down an inclined plane with a constant acceleration of 2 5 m s2. Assuming that the player accelerates uniformly determine the distance he runs.

The ball s kinetic energy just after the bounce is less than just before the bounce. If the ball accelerates uniformly when it hits the floor what is the approximate acceleration as it comes to rest before rebounding. If the book takes 1 0 s to fall to the floor calculate. The details of the rebound are specified in tennis regulations.

Problem 72pp from chapter 10. If the car traveled 190 m during this 12 second period what was the velocity of the car when it started to accelerate. The student predicts the time to fall using g as 9 80 m s2 but finds the measured time to be 35 greater. If the ball accelerates uniformly when it hits the floor wh.

In getting ready to slam dunk the ball a basketball player starts from rest and sprints to a speed of 11 0 m s in 2 58 s. A car starts from rest and accelerates uniformly for 8 0 s. It reaches a final speed of 16 m s 1. A student is testing the kinematic equations for uniformly accelerated motion by measuring the time it takes for light weight plastic balls to fall to the floor from a height of 3 m in the lab.

B calculate its velocity just after it leaves the floor on its way back up. By what percent does the kinetic energy decrease. A strategic approach with masteringphysics 0th edition edit edition. If the ball accelerates uniformly when it hits the floor what is its approximate acceleration as it comes to rest before rebounding.

I got the right answer of 4000 m s 2 c. Solution for a tennis ball bouncing on a hard surface compresses and then rebounds.
