# The masses of the blocks are m1 = 16.0 kg and m2 = 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 m2 is initially on the floor, and block m1 is initially 4.60 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 m1 to hit the floor after being released? 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 m1 to hit the floor if the mass of the pulley were neglected.)
