a long narrow uniform stick of length and mass lies motionless on a frictionless surface of ice. the moment of intertia of the stick about its center of mass is . a puck of mass slides without spinning on the ice with a velocity toward the stick, collides elastically with one end of the stick, and rebounds in the opposite direction with velocity . after the collision, the center of mass of the stick moves with velocity , and the stick rotates about the center of mass with angular velocity . assume that the radius of the puck is much less than the length of the stick so that the moment of inertia of the puck about its center of mass is negligible compared to . in this problem you will find the magnitude of the angular velocity of the stick after the collision. (part a) what concepts should you apply to this problem? this answer cannot be checked online.
