Question

021 (part 1 of 2) 10.0 points A student sits on a rotating stool holding two 1 kg objects. When his arms are extended horizontally, the objects are 1 m from the axis of rotation, and he rotates with angular speed of 0.79 rad/sec. The moment of inertia of the student plus the stool is 4 kgm2 and is as- sumed to be constant. The student then pulls the objects horizontally to a radius 0.36 m from the rotation axis Calculate the final angular speed of the student Answer in units of rad/s 022 (part 2 of 2) 10.0 points Calculate the change in kinetic energy of the system Answer in units of J
