A 38.0 kg wheel, essentially a thin hoop with radius 1.30 m, is rotating at 280 rev/min. It must be brought to a stop in 13 s. How much work must be done to stop it? Why isn't translational kenetic energy accouted for in this question? I only used rotational kenetic energy for my answer and I appeared to get the right answer. Can you please explain or correct me if I'm wrong.

A potter's wheel—a thick stone disk of radius 0.500 m and mass 125 kg—is freely rotating at 50.0 rev/min. The potter can stop the wheel in 6.00 s by pressing a wet rag against the rim and exerting a radially inward force of 71.0 N. Find the effective coefficient of kinetic friction between the wheel and rag.

A thin hoop (I = 1.31 kg m^2) is rotating with an angular velocity of 4.6 rad/s. Five identical globs of putty are then attached to the rotating hoop. If the hoop has a radius of 0.52 m and each particle-like piece of putty had a mass of 0.45 kg, what would be the angular velocity of the resulting hoop-putty system? A. 2.8 rad/s B. 3.1 rad/s C. 4.2 rad/s D. 3.6 rad/s
