The motor M is at rest whensomeone flips a switch and it starts pulling in the rope. Theacceleration of the rope is uniform and it takes 1s to achieve aretraction rate of 4ft/s. After 1s the retraction rate becomesconstant. Determine the tension in the cable during and after theinitial 1s interval. The cargo C weighs 130lb, Pulleys A and B eachweigh 12lb, and the weight of the cable is negligible. Neglectfriction in the pulleys and the rotational inertia of thepulleys.
