A jewelry box of mass 1 kg is attached to the end of a thin string. The string is wound around a solid, uniform disk of mass 6 kg and radius 10 cm. The disk rotates about a fixed axis that passes through its center. What is the speed of the box right before hitting the ground if the box is released from rest from a height of 1m above the ground?
