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!
