The belt-driven pulley and attached disk are rotating with increasing angular velocity. At a certain instant the speed v of the belt is 1.2 m/s, and the total acceleration of point A is 39 m/s². For this instant determine (a) the magnitude of the angular acceleration of the pulley and disk, (b) the magnitude of the total acceleration of point B, and (c) the magnitude of the acceleration of point C on the belt.
