Problem 3. A potter's wheel of radius 0.19m and mas 82.10 kg is freely rotating at 46.0 rev/min. The potter can stop the wheel in 8.4 s by pressing a wet rag against the rim a. What is the angular acceleration of the wheel? In rad/s^2. Note: Is the formula to use in this problem t=I*a?Where I is moment of inertia and a = angular acceleration. How would the data in the problem be set up in the formula?
