The pulley system in the figure is used to lift a crate of mass m=50kg. Note that a chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume that the masses of the chains, pulleys, and ropes are negligible. Determine the tension in the rope when the crate is being lifted with constant speed.
