A man is attempting to lift a crate using a two part pulley system. The crate has mass m2 = 74 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 505 N. The pulleys are massless and frictionless.
a. Using T to describe the magnitude of the tension force, write an expression for the sum of the forces in the y-direction acting on the crate in terms of gravity and the variables provided.
b. Using the results from above, write an expression for the crate's vertical acceleration, ac, in terms of T.
c. What is the magnitude of the tension force, T in newtons?
d. What is the block's acceleration, ac, in m/s2?
