SO to calculate work = FD is it as simple as the distance the rope is pulled * mass of the wt *g. and Power would be divided by the time it takes to pull the distance or is there something specific with a pulley system that needs to be take into account?

See attachment :)

Forces on a weight stack with the position of the pulleys so the weight is pulled up and the puller is moving a horizontally. Is it correct to use F=MG?
