Obtain the speed of the block after it has fallen

Reference no: EM13678221

A 1.2 kilogram block is tied to a string that is wrapped around the rim of a pulley of radius 7.3 centimeter. The block is released from rest.

Part A Assuming the pulley is a uniform disk with a mass of 0.31 kilogram, obtain the speed of the block after it has fallen through a height of 0.50 meter.

(m/s)

Part B If a small lead weight is attached near the rim of the pulley and this experiment is repeated, will the speed of the block increase, decrease, or stay the same?
