A Tennis ball is released from a height h and after freelyfalling on a wooden floor it rebounds and reaches height2h . The velocity versus height of the ball during its motionmay be represented graphically by :(graph are drawn schematically and on not to scale

A ball is thrown vertically upwards. Which of the following graph represent velocity-time graph of the ball during its flight (air resistance is neglected)

A ball is dropped on a floor and bounces back to a height somewhat less than the original height. Which of the curves depicts its motion correctly?

As a ball falls towards ground, its velocity _____

A ball A is thrown vertically upwards with speed u. At the same instant another ball B is released from rest height h. At times t, the speed of A relative to B is :-

A ball is dropped on the ground from a height of 1m. the coefficient of restitution is 0.6. The height to which the ball will rebound is :-    0.6 m        0.4 m    0.36 m        0.16 m
