A string is wrapped around a disk of mass m = 1.9 kg and radius R = 35 m, which is fixed to an axle that goes through its center. You pull the string with a constant force F = 8 N to unravel it. The torque is of 5.45 Nm due to friction between the axle and the disk. The moment of inertia of a solid disk rotating about its center is given by I = MR2 /2. What is the angular acceleration of the disk, in units of radians per second squared (rad/s2). Assuming it starts from rest, how fast will the disk be spinning after the string is pulled for 3.00 seconds? Give your answer in revolutions per minute (rpm).
