A 200-Ib block is suspended from an inextensible cable which is wrapped around a drum of 1.3-ft radius rigidly attached to a flywheel. The drum and flywheel have a combined centroidal moment of Inertia IG=10 Ib-ft-s^2 At the instant shown, the velocity of the block is 5 ft/s directed downward. Knowing that the bearing at A is poorly lubricated and that the bearing friction is equivalent to a couple M of magnitude 60 Ib-ft, determine the work or U1->2 (in ft-Ib) after it has moved 4.2 ft downward
