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 hoop (thin walled hollow cylinder) of mass 2.3 kg, radius 0.37 m, is rotating at 6.39 radians/s about the symmetric axis. Calculate its rotational kinetic energy in Joules to 2 significant figures Answer: I
a wheel consists of a thin hoop (m= 0.50 kg and radius= 0.50 m) with 16 spokes (m= 0.010 kg and length 0.50 m). What is the wheels moment of inertia?
A potter's wheel having a radius of 0.500 m and mass 45.0 kg is rotating freely at 50.0 rev/min in a clockwise direction. The potter can stop the wheel by pressing a wet rag against the outside rim of the wheel and exerting a radially inward force of 70.0 N. Since this force is in the radial direction, it alone cannot cause the wheel to slow its spinning. What can happen, however, is that a normal force can result from...
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.
