Suppose you exert a force of 195 N tangential to the outer edge of a 1.41-m radius 77.5-kg grindstone (which is a solid disk). 1) What is the torque τ, in newton meters, you are exerting on the grindstone, relative to the center of mass of the grindstone? τ = 2) What is the angular acceleration of the grindstone α0, in radians per square second, assuming negligible friction? α0 = 3) What is the angular acceleration of the grindstone αf, in radians per square second, if there is an opposing frictional force of 20.5 N exerted 0.35 m from the axis?
