A light string is wrapped around a solid uniform disk of radius 25.0 cm and mass 0.500 kg. The pulley is initially rotating at 5.00 rad/s. A constant force of 30.0 N is applied to the string, which does not slip, causing the pulley to rotate and the string to unwind. The torque exerted by friction at the axle has a magnitude of 5.00 N-m. Part A Find the angular acceleration of the disk. Express your answer with the appropriate units. Part B Determine the angular velocity of the disk after a time of 0.300 S. Express your answer with the appropriate units. Part C In radians, find the angular displacement of the disk in that time. Input your numerical answer.
