The motor M is at rest when someone flips a switch and it starts pulling in the rope. The acceleration of the rope is uniform and such that it takes 0.50 s to achieve a retraction rate of 7.00 ft/s. Determine the tension in the rope during initial 0.50 s. The cargo C weighs 2576 Ib., the weight of the ropes and pulleys is negligible, and friction in the pulleys is negligible. Note: answer to be in pounds (Ib).
