# Homework Help: How to predict how far a spinning ball will bounce?

1. The problem statement, all variables and given/known data
If I were to drop a spinning ball vertically, the spin would cause the ball to bounce a certain horizontal difference. Intuitively, the rougher the surface it bounces against, the further the ball should bounce. How would you quantify this relationship?

2. Relevant equations

3. The attempt at a solution
I honestly have no idea where to start, which is why I'm posting here xD

Thanks!

Welcome to PF!
Your question has not much sense. Write the whole text of the problem.
And fill in the template. What are the relevant equations? What is angular velocity? How friction can influence it? You also need to show some attempt to solve the problem.

In general angular velocity of a rotating body is not related to some coefficient of friction. What is the relationship between the angular velocity of the rotating Earth to the coefficient of friction between rubber and asphalt, for example????
