The two masses (m1 = 5.0 kg and m2 = 3.0 kg) in the Atwood's machine shown in FIGURE 10-33 are released from rest, with m1 at a height of 0.75 m above the floor. When m1 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) and determine the pulley's mass.
