Homework Statement



How is the height if the ball affected by the surface of which it bounces? And does it have something to do with the formula below? What does the formula mean in a easy to understand manner? Thanks a lot!

Homework Equations



e = (V2 - V1) / (U1 - U2)

The Attempt at a Solution



i think it has something to do with the amount of harness the surface has.

well, the coeficient of restitution means the amount of energy that is lost due to the colision.
