If The Ball Accelerates Uniformly When It Hits The Floor

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.

When dropped from a height of 2 5 monto a concrete surface a ball must rebound to a height of 1 4 m. The ball s kinetic energy just after the bounce is less than just before the bounce. A car starts from rest and accelerates uniformly for 8 0 s. 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.

Solution for a tennis ball bouncing on a hard surface compresses and then rebounds. Problem 72pp from chapter 10. I got the right answer of 4000 m s 2 c. A girl hits a ball so that it hits a rock and travels straight up into the air.

If the ball accelerates uniformly when it hits the floor what is the approximate acceleration as it comes to rest before rebounding. Assuming that the player accelerates uniformly determine the distance he runs. A book is knocked off a bench and falls vertically to the floor. It reaches a final speed of 16 m s 1.

The details of the rebound are specified in tennis regulations. 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 if the ball accelerates uniformly when it hits the floor what is its approximate acceleration as it comes to rest before rebounding. 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.

If the car traveled 190 m during this 12 second period what was the velocity of the car when it started to accelerate. How fast is the ball moving when it hits the concrete surface. During impact the ball compresses by approximately 6 mm. If the ball accelerates uniformly when it hits the floor what is its approximate acceleration as it comes to rest before rebounding.

If the book takes 1 0 s to fall to the floor calculate. By what percent does the kinetic energy decrease. If the ball accelerates uniformly when it hits the floor wh. A ball rolls down an inclined plane with a constant acceleration of 2 5 m s2.

When a tennis ball bounces from a racket the ball loses approximately 30 of its kinetic energy to thermal energy. A car initially traveling with a uniform velocity accelerates at a rate of 1 0 m s2 for a period of 12 seconds.
