A ball after falling a distance of 5 meter rest hits elastically the floor of a lift and rebounds. At the time of impact the lift was moving up with a velocity of 1m/sec. The velocity with which the ball rebounds just after impact is : `(g=10m//sec^(2))`

A ball falls from a height such that it strikes the floor of lift at 10 m/s. If lift is moving in the upward direction with a velocity 1 m/s, then velocity with which the ball rebounds after elastic collision will be

A ball falls from a height of 5 m and strikes a lift which is moving in the upward direction with a velocity of 1 m s^(-1) , then the velocity with which the ball rebounds after collision will be

A small ball falling vertically downward with constant velocity 2 m//s strikes elastically an inclined plane moving with velocity 2 m//s as shown in figure. The velocity of rebound of the ball with respect ground is

A bouncing ball of mass 200 g falls from the height of 5m on a horizontal ground. After every impact with the ground, the velocity of the ball decreases by (1)/(2) times. The total momentum the ball imparts on to the ground after 3 impacts is (Let g=10m//s^(2) )

A ball is dropped from a height of 20 m and rebounds with a velocity which is 3/4 of the velocity with which it hits the ground. What is the time interval between the first and second bunces (g=10m//s^(2))
