A 160 lb person is being pulled on a tube in the snow by a four wheeler when the four wheeler starts to spin at 3 rad/s. Initially, the person on the tube is 12 feet from the center of rotation when the towing rope gets wrapped around the axle and begins to pull in at 3 ft/s. Determine the velocity of the person and the tube when they are 4 feet from the center of rotation. Neglect the mass of the four wheeler, tube, and towing rope. Assume the tube is on a smooth surface and that angular momentum is conserved. (108.0 ft/s)
