If The Ball Accelerates Uniformly When It Hits The Floor

A ball rolls down an inclined plane with a constant acceleration of 2 5 m s2.

If the ball accelerates uniformly when it hits the floor.

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. The details of the rebound are specified in tennis regulations. If the ball accelerates uniformly when it hits the floor what is its approximate acceleration as it comes to rest before rebounding. It reaches a final speed of 16 m s 1.

The ball s kinetic energy just after the bounce is less than just before the bounce. 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. Assuming that the player accelerates uniformly determine the distance he runs. If the car traveled 190 m during this 12 second period what was the velocity of the car when it started to accelerate.

A girl hits a ball so that it hits a rock and travels straight up into the air. By what percent does the kinetic energy decrease. How fast is the ball moving when it hits the concrete surface. A car initially traveling with a uniform velocity accelerates at a rate of 1 0 m s2 for a period of 12 seconds.

The student predicts the time to fall using g as 9 80 m s2 but finds the measured time to be 35 greater. When dropped from a height of 2 5 monto a concrete surface a ball must rebound to a height of 1 4 m. A strategic approach with masteringphysics 0th edition edit edition. I got the right answer of 4000 m s 2 c.

During impact the ball compresses by approximately 6 mm. If the book takes 1 0 s to fall to the floor calculate. A car starts from rest and accelerates uniformly for 8 0 s. If the ball accelerates uniformly when it hits the floor what is the approximate acceleration as it comes to rest before rebounding.

A calculate its velocity just before it strikes the floor. Problem 72pp from chapter 10. If the ball accelerates uniformly when it hits the floor wh. A book is knocked off a bench and falls vertically to the floor.

B if the ball accelerates uniformly when it hits the floor what is its approximate acceleration as it comes to rest before rebounding. 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.
