The system shown below is released from rest. The m, = 27 kg block is 2 m above the ledge. The pulley is a úniform disk with a radius of 10 cm and mass m = 6.0 kg. Assume that string does not slip on the pulley. T= 10 cm 2 m 20kg (a) Find the speed of the 27 kg block just before it hits the ledge. m/s (b) Find the angular speed of the pulley at that time. rad/s (c) Find the tensions in the strings. N (left)
