A circular pulley of radius 0.35 [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 4.00 [m] from the ground. If the speed of the block right before it hits the ground is 9.0 [m/s], what is the angular acceleration of the pulley? a) 2.90 rad/s^2 b) 10.1 rad/s^2 c) 28.9 rad/s^2 d) 48.1 rad/s^2
