A ball is dropped vertically from a height above the ground. It hits the ground and bounces up vertically to a height d/2. Neglecting air resistance its velocity varies with the heighth above the ground as:

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
a
The graph between h and v will be a parabola as `vpropsqrt(h)` .At h =d the velocity is zero .Then its negative value increase At h=0 the velocity gets reveresed and then goes on decreasing and become zero at h=d/2.
