A potter's wheel is a uniform solid disk of diameter 0.72m and a mass of 60kg. the wheel is initially spinning at a rate of 85 rev/min. and the potter wants to bring it down to 45 rev/min with her hands within 15 revolutions.

A) what is moment of inertia of the disk?

B) what is angular acceleration that wil bring down the rotational speed under the states conditions?

C) what minimum total friction force must tthe potter supply to the disk if her hands are acting at the edge of the disk?
