A man is attempting to lift a crate with a double-pulley system, as shown. A single rope is routed from the ceiling, through the two pulleys, and to where the man pulls on it. The crate has mass m2 = 89 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 616 N. The pulleys are both massless and frictionless, and the rope is ideal.
