Explanation : According to the law of conservation of angular momentum, the person on the rotating table will maintain approximately the same angular momentum during the spin. lf he moves his arms in, he will reduce the rotational inertia by reducing the distance of the mass of arms and hands from the axis of rotation. In order to maintain the same angular momentum, angular rotation is increased. However, when the person spreads his hands outward, the angular rotation is decreased and the spin becomes slower. ....Read more
