Ball/Court Interaction

Let's look at the angle out now. In the sections on coefficient of friction and coefficient of restitution we learned that these parameters drive the speed of the court, rebound height, rebound distance, and angle out. What would we expect to see? Brody's book tells us that the friction between the ball and court will:

causes the angle out to change from the angle in;
the smaller the friction the smaller the rebound angle;
the smaller the friction the faster the court. Why? The ball tends to slide or skid over the surface of the court versus really rub against it.
the larger the friction the greater the rebound angle;
the greater the friction the slower the court. Why? The ball rubs heavily against the court slowing it down.
