A disk is attached to an axle, about which it can freely rotate without friction. The axle is parallel to the floor, and the disk has a mass of 3.50 kg and a diameter of 47.4 cm. The disk is held so that its center of mass is as high as the axle, and then released from rest. What is the angular velocity of the disk when it is directly below the axle?
