A person is pulling downward with a force of 120.0 N on a cord wrapped around a pulley of diameter 66.0 cm. The force is applied counter-clockwise at an angle of 45 degrees to the vertical. If the moment of inertia of the pulley is 0.269 kg.m^(2) and there is also a frictional torque of 1.10 N.m at the axle, what is the angular acceleration of the pulley? (Let counter-clockwise represent the positive direction of rotation). O a. 204 rad/s^(2) O b. 314 rad/s^(2) O c. 143 rad/s^(2) O d. 100 rad/s^(2)
