Basketball free-throw rebound motions

A dynamic model is used to analyze the rebounding ball trajectories of free throws. The dynamic model previously described calculates slipping and non-slipping, and spinning and non-spinning motions at the contact point. First ball-contact boundaries for rebounds are estimated in the release velocity and angle space. We show the geometry of ball trajectories for rebounds of free throws with lateral deviation at the release point. The distances and positions for free-throw rebounds are analyzed.
