J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m
A ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?

A 900 g rubber ball is dropped from height 17.5 m, and it rebounds to height 5.17 m. Assuming there is no air friction and the average force exerted by the ground is 24.5 N, find the time the ball was in contact with the ground.
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.
