Two blocks are connected to a string, and the string is hung over a pulley connected to the ceiling, as shown in the figure below. Mo R The masses of the blocks are m, = 17.0 kg and m, = 12.0 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.300 m. Block m, is initially on the floor, and block m, is initially 4.40 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the string is small enough to be ignored, and the string does not slip on the pulley, nor does it stretch. (a) How much time (in s) does it take block m, to hit the floor after being released? At, = 2.37

(a) How much time (in s) does it take block m, to hit the floor after being released? At, = 2.37 (b) How would your answer to part (a) change if the mass of the pulley were neglected?
