Please describe step by step for each step

A potter's wheel having a radius of 0.50 m and a moment of inertia of 12 kg . m is rotating freely at 50 rev/min (5.2 rad/s) counterclockwise. The potter can stop the wheel in 6.0 s by pressing a wet rag against the rim and exerting a radially inward force of 70 N. Find the effective coefficient of kinetic friction between the wheel and the wet rag in the following steps: (a) Sketch an overhead diagram of the wheel, indicate which way the wheel is rotating (4 points) (b) Draw a free-body diagram and include the normal force and force of friction, and indicate which way the angular acceleration is. (4 points) (c) How much torque do each of these forces generate on the wheel? (You will have formula at this stage) (4 points) (d) Write down Newton's 2nd Law for a rotating system. (4 points) (e) Write a kinematic equation that can help you find the angular acceleration. (4 points) (f) Use the above equations to solve for the friction force (5 points)
