A ball of mass 81 kg is dropped from a height of 22 m. What is the height at which the velocity is exactly half of the final velocity with which it hits the ground?
A steel ball is dropped onto a hard floor from a height of 1.575 m and rebounds to a height of 1.3 m
A steel ball is dropped onto a hard floor from a height of 1.575 m and rebounds to a height of 1.3 m. Use a coordinate system in which the vertical component of velocity is positive in the upwards direction. Part (a) Calculate its velocity, in meters per second, just before it strikes the floor.

A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)

(Assume there is no air resistance.) A ball of mass m and another ball of mass 3m are dropped. The two balls have the same kinetic energy when they hit the ground. If the ball of mass m was dropped from height h, the height of the ball of mass 3m dropped is h/3. Explain why.
A tennis ball is dropped from a height of 5 m to the ground and the ball rebounded to a height of 4 m
A tennis ball is dropped from a height of 5 m to the ground and the ball rebounded to a height of 4 m. If the mass of the basketball is 1.0 kg and it is in contact with the floor for 50 ms, determine the average force exerted by the ground to the basketball.

A 0.2 Kg ball is dropped with no initial velocity from a height of 6 m. It drops vertically with no air drag, it hits the flat, concrete ground and re-bounces upward in a vertical direction reaching a maximum height of 4 m. (i) Calculate the speed of the ball when it hit the ground. (ii) Calculate the speed of the ball when it began moving upward. (iii) Calculate the magnitude of the impulse provided by the ground to the...

A rock is dropped from a height of 110 meters above the ground. One second later, a ball is thrown vertically downward from the same height with an initial speed of 14 m/s. A. At what time after the ball if thrown are the two objects at the same height above the ground? B. What is the speed of the rock when the ball hits the ground?
