A student sits on a freely rotating stool holding two weights, each of mass 3.08 kg. When his arms are extended horizontally, the weights are 0.91 m from the axis of rotation and he rotates with an angular speed of 0.755 rad/s. The moment of inertia of the student plus stool is 3.08 kg·m2 and is assumed to be constant. The student pulls the weights inward horizontally to a position 0.294 m from the rotation axis. (a) Find the new angular speed of the student. rad/s (b) Find the kinetic energy of the rotating system before and after he pulls the weights inward. J (before) J (after)
