The velocity -time of a body falling from rest under gravity and rebounding from a solid surface is represented by which of the following graphs?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
Initially velocity increases downwards (negative) and after rebound it becomes positive and then speed us decreasing due to acceleration of gravoty `(darr)`
