A man holds 1.0 kg weight in each of his hands while sitting on a chair which can rotate freely with negligible friction. When the man stretches his arms, he is rotating at angular speed 1.5 rad/s. Assume his arms can be modeled as a uniform rod with mass 2.0 kg and length 2.0 m. (a) The initial angular momentum (b) The final angular speed when he folds half of his arms and holds the weights at the center of axis. (c) The final angular speed when he drops the two weights but remains his arms straight. 1 it Rotation axis (a) 74 a CARCANGAN (b)
