19. Mr. Lamp. A block with mass 10.0 [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 9.00 [rad/s]. What is the angular acceleration of the pulley? A. 2.20 [rad/s²] B. 5.71 [rad/s²] C. 22.7 [rad/s²] 2.50m D. 47.4 [rad/s²]
