consider the acceleration velocity and displacement of a tennis ball as it falls to the ground and bouces back. Derections of which of these changes in the process

A

velocity only

B

displacement and velocity

C

acceleration, velocity and displacement

D

displacement and acceleration

Text Solution

Verified by Experts

The correct Answer is:
B
Only direction of displacement and velocity gets changed, acceleration is always directed vertically downward.
