Two blocks are connected to a cord, and the cord is hung over a pulley connected te the celling, as shown in the figure below GMy Notes Ask Your Teacher M R The masses of the blocks are m,-17.0 kg and m, 12.0 kg, the mass of the puliey is M S.00 kg, and the radius of the puley is R 0.300 m. Block m, is intially on the flo0s, and block m, is initially 4.10 m above the floor when it is released from rest. The pulley's axis has negligibile 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 At, (b) How would your answer to part (a) change if the mass of the puley were neglected? (Enter the time, in seconds, it takes block m, to hit the foor if the mass of the puley were neglected.)
