Homework Statement
The two masses (m1 = 5.0 kg and m2 = 3.0 kg) in the Atwood's machine shown in Figure 10-23 are released from rest, with m1 at a height of 0.92 m above the floor. When m1 hits the ground its speed is 1.1 m/s. Assume that the pulley is a uniform disk with a radius of 12 cm.
Determine the pulley's mass.
