Two blocks are connected to a cord, and the cord is hung over a pulley connected to the ceiling, as shown in the figure below. MOR m1 mo The masses of the blocks are m = 17.0 kg and m2 = 11.5 kg, the mass of the pulley is M = 5.00 kg, and the radius of the pulley is R = 0.300 m. Block m2 is initially on the floor, and block mis initially 4.60 m above the floor when it is released from rest. The pulley's axis has negligible friction. The mass of the cord is small enough to be ignored, and the cord 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? At1 = S (b) How would your answer to part (a) change if the mass of the pulley were neglected? (Enter the time, in seconds, it takes block m, to hit the floor if the mass of the pulley were neglected.) Atz =
