Question

A thick stone disk with a radius of 15.0 cm and a mass of 9.00 kg is freely rotating at 60.0 rpm. A chunk of clay with a rotational inertia of 0.0250 kg m2 about the spinning axis is stuck on the wheel. The potter can stop the wheel over 5.00 seconds by pressing a rag against the edge of the wheel.

a. What is the total initial angular momentum? (Give your answer in N m s.)total rotational inertia is equal to the rotational inertia of the disk (Idisk = 1/2 MR2) plus the rotational inertia of the clay.

b. What frictional torque does the potter apply to bring the wheel to a stop? (Give your answer in N m.)
