An 0.10-kg apple is connected to a string that is wrapped around the circumference of a nonuniform thin disk of radius R = 0.35 m and mass m = 0.20 kg, as shown at right. The disk is held in place by a wire connected to the other side of the disk 3 horizontal distance r from the central axle. The wire is cut at time t = 0 and the apple begins to move downward. The magnitude of the angular acceleration of the disk is 11.0 radlsz. You are looking to the east at the disk. _' 1 If before the wire is cut the central axle exerts an upward force of 4.5 N on the disk, what is the horizontal distance r from the wire to the center of the disk? 2 What is the angular velocity of the disk when it has rotated 90? 3 What is the angular displacement of the disk at time t= 0.50 s? 4 What is the moment of inertia of the disk? wire I axle ' W 'H 1" Hi...
