The pulley system shown in the figure is used to lift a 53 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 that the masses of the chains, pulleys, and ropes are negligible and the crate is rising with an acceleration of 3.4 m/s2.
(a) Determine the force .
1 0.35
Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kN
(b) Determine the tension in the upper chain.
1 kN
(c) Determine the tension in the lower chain.
1 kN
