A Solid Uniform 3

question 159

Short Answer

A solid uniform 3.33-kg disk has thin string of negligible mass wrapped around its rim, with one end of the string tied to the ceiling, as shown in the figure. The disk is released from rest, and as it falls, it turns as the string unwraps. At the instant its center has fallen 2.25 m, (a)how fast is the center moving, and (b)how much rotational kinetic energy does the disk have?
