A crate A with weight WA = 250 lb is hanging from a rope wound around a uniform drum D of radius r = 1.2 ft, weight = 125 lb, and center C. The system is initially at rest when the restraining system holding the drum stationary fails, thus causing the drum to rotate, the rope to unwind, and, consequently, the crate to fall. Assuming that the rope does not stretch or slip relative to the drum and neglecting the inertia of the rope, determine the speed of the crate 1.5 s after the system starts to move.
