Homework Equations

The mass fixed to the other end of the pulley is 200 kg.

The Attempt at a Solution

I was under the impression that if one side of the pulley pulled down with 1960 N (200 kg * 9.81 ms^-2) then the tension in the winch would be the same as well.
Can anyone shed some light on this?

Is the mass is accelerating? So the forces on the 200 kg mass sum to _____? What are the forces? If there was any difference in the tension of the rope along the rope, what would have to occur?
