The two masses (m 1 = 5.0 kg and m2 = 3.0 kg) in the Atwood’s machine shown in are released from rest, with m 1 a t a height of 0.75 m above the floor. When m 1 hits the ground its speed is 1.8 m/s. Assuming that the pulley is a uniform disk with a radius of 12 cm, (a) outline a strategy that allows you to find the mass of the pulley. (b) Implement the strategy given in part (a) arid determine the pulley’s mass.
