Physics

To find the percentage of speed lost during the rebound, we calculate the speeds before and after the rebound using the heights and then determine the percentage decrease.

 

Given:

Initial height () = 3.2 m

Rebound height () = 1.8 m

 

Calculate the velocity before impact ().

The speed just before impact is calculated using:

 

 

Calculate the velocity after rebound ().

Using the same formula for the rebound height:
