coefficient of kinetic friction

*19–12. The 40-kg roll of paper rests along the wall where the coefficient of kinetic friction is mk = 0.2. If a vertical force of P = 40 N is applied to the paper, determine the angular velocity of the roll when t = 6 s starting from rest. Neglect the mass of the unraveled paper and take the radius of gyration of the spool about the axle O to be kO  = 80 mm.
