Problem 1 A circular pulley of radius 0.45 [m] can rotate on frictionless bearing. A massless string passes around the pulley and is attached to a block with mass 10.0 [kg]. The block is then dropped from a height of 5.00 [m] from the ground. If the speed of the block right before it hits the ground is 13.0 [m/s], what is the angular acceleration of the pulley?
