Answer to Question #205367 in Physics for manatee

Question

A block with mass 10 [kg] is attached to

a string tightly wound to circular frictionless pulley of

radius 0.300[m]. The block is dropped from a height of

2.50 [m] from the ground. Right before the block hits the

ground, the pulley of unknown mass was found to have

an angular velocity of 9 [rad/s]. What is the angular

acceleration of the pulley?
