Reference no: EM13694753

Solve the all parts of following question given below:

Question: A solid uniform 3.33 disk has a string of negligible mass wrapped around its rim, with one end of the string tied to the ceiling. The disk is released from rest and as the disk falls, the string unwraps. At the instant the center of the disk has fallen 2.25 m determine the following:

Part I: How fast is the disk moving?

Answer in m/s.

Part II: How much rotational kinetic energy does the disk have?

Answer in Joules.

Please show all work and steps and clearly explain. Thanks.
