Atwoods machine the two masses m1 51kg and m2 25kg in, Ask an Expert

Academics

Atwood's Machine The two masses (m1 = 5.1kg and m2 = 2.5kg ) in the Atwood's machine are released from rest, with m1 at a height of 0.95m above the floor. When m1 hits the ground its speed is 1.8m/s. Assuming that the pulley is a uniform disk with a radius of 12 cm. Determine the pulley's mass. Please show all formulas and work.
