please help The pulley system shown in the figure is used to lift a m= 67-kg crate. Note that one chain connects the upper pulley to the ceiling and a second chain connects the lower pulley to the crate. Assume the masses of the chains, pulleys, and ropes are negligible.
Determine the force F required to lift the crate with constant speed.
Express your answer using two significant figures.
F = kN
Part B
Determine the tension in the upper chain.
Express your answer using two significant figures.
Cupper = kN
Part C
Determine the tension in the lower chain. c upper= kn
