b) A grindstone in the shape of a solid disk with diameter 0.520 m and a mass of 50.0 kg is rotating at 850 rev/min. You press an axe against the rim with a normal force of 160 N (see below), and the grindstone comes to rest in 7.50 s. Find the coefficient of kinetic friction be- tween the axe and the grindstone. There is negligible friction in the bearings.

In a home laundry dryer, a cylindrical tub containing wetclothes is rotated steadily about a horizontal axis, as shown inFigure P7.61. So that the clothes will dry uniformly, they aremade to tumble. The rate of rotation of the smooth-walled tubis chosen so that a small piece of cloth will lose contact withthe tub when the cloth is at an angle of θ = 68.0° above thehorizontal. If the radius of the tub is r = 0.330 m, what rate ofrevolution is needed in revolutions per second?
