if the pulleys are massless and frictionless and the rope is of negligible mass, and aristotle wanted to raise the 332 newton weight to a height of 6 meters.

A-find the magnitude of force F he needed to pull on the rope to move the weight upward with a constant velocity.

B-What was the mechanical advantage of the pulley system?

C-How far did he have to move his end of the rope?

D-how much work did he do?

E-how much work was done on the weight?

I know this is kind've a long one, ty
