3. A student sits on a freely rotating stool holding two dumbbells, each of mass 2.92 kg. When his arms are extended horizontally, the dumbbells are 0.95 m from the axis of rotation and the student rotates with an angular speed of 0.754 rad/s. The moment of inertia of the student plus stool is 2.69 kg · m2 and is assumed to be constant. The student pulls the dumbbells inward horizontally to a position 0.305 m from the rotation axis....
