A potter’s wheel consists of a uniform concrete disk, 0.035 m thick and with a radius of 0.42 m. It has a mass of 48 kg. The wheel is rotating freely with an angular velocity of 9.6 rad/s when the potter stops it by pressing a wood block against the edge of the wheel, directing a force of 65 N on a line toward the center of the wheel. If the wheel stops in 7.2 seconds, what is the coefficient of friction between the block and the wheel?
