Question: The 18-lb cradle is supported as shown by two uniform disks that roll without sliding at all surfaces of contact. The weight of each disk

The 18-lb cradle is supported as shown by two uniform disks that roll without sliding at all surfaces of contact. The weight of each disk is W = 12 lb and the radius of each disk is r = 4 in. Knowing that the system is initially at rest, determine the velocity of the cradle after it has moved 15in.
