A man is attempting to lift a crate using a two part pulley system as shown in the image. The crate has mass m2 = 53 kg, and the man has m1 = 75 kg. He pulls downward on the rope with a force of magnitude F = 659 N. The pulleys are massless and frictionless. 1.) 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. 2.) what is the blocks acceleration in m/s^2?
