Use the information below to answer the three (3) following questions: A cylindrical grindstone of mass m = 18 kg and radius R = 0.8 m is initially rotating freely at 26π radians/s.  An axe is brought into contact with the grindstone which brings it to a stop after 30 revolutions. What is the direction of the torque due to the frictional force of the axe on the grindstone?
