Physics

To calculate the change in the ball's velocity during the rebound, we will determine the velocity just before hitting the ground and just after the rebound, then compute their difference.

 

Use the equation of free fall to calculate velocities

The velocity is given by:

Where:

(acceleration due to gravity),

is the height.

 

Velocity before hitting the ground ():

 

Velocity after rebounding ():
