A student sits on a freely rotating stool holding two weights, each of mass 4.28kg (see the attached figure). When his arms are extended horizontally, the weights are 0.56 m from the axis of rotation and he rotates with an angular speed of 0.86 rad/s. The moment of inertia of the student plus stool is 3.07kg m2 and is assumed to be constant. The student pulls the weights inward horizontally to a position 0.28 m from the rotation axis. Find the kinetic energy of the rotating system after he pulls the weights inward.
