- a 9. A potter's wheel – a solid stone disk of radius 0.5m and mass 100kg – is freely rotating at 16.Orad/s. The potter can stop the wheel in 20.0s by pressing a wet rag against the rim directly toward the axle (.e. radially inward) with a force of 50N. What is the coefficient of kinetic fiction between the rim of the wheel and the rag? (Answer: 0.4)
