TEAM 379 1 The Physics of a Three-Point Shot Team 379 I. INTRODUCTION governs the rules of international basketball including the great American pastime, basketball raises many inter- Olympics [3]. Aesting questions for the curious physicist. By studying the physics behind a basketball shot, physicists can develop insight into the shooting conditions most likely to result in a successful shot, and therefore may help basketball players focus their training on the parameters most likely to imporve their performance. In this paper, we focus our study on shots taken from the three-point line, and investigate what combinations of spin and initial velocity result in the ball entering the net. Determining the set of velocities and spins necessary to successfully shoot a basket requires a discussion of projectile motion as well as the kinematics of colliding bodies. In ord
