A brake mechanism is used to lower body A with a constant velocity of 3.0 m/s. The coefficient of friction between the brake and drum D is 0.40. Neglect the weight of the brake. Determine the mass of body A and the power dissipated by the brake. (hint: the normal force between the brake the and disk is not 1200 N)
