Solution of this question

I confused. what the question?

work in = F * d = 80 N * 0.20 meters = 16 Joules
if all is perfect work out = work in
200 N * h = 16
h = 0.08 meters = 8 centimeters

White lifting a load of 200N using aload an effort of 80N moved through a distance of 20cm to lift a load through a distance of 4cm to calculate (a) mechanical advantage and velocity ratio

I dont now
