If you lift a 200 newton box 1 meter with a rope and is the system and you apply 20 newtons to lift this box, what to mechanical advantage of the system? how far do you have pull the rope when you are applying the input force? if you do this work in 5 seconds, what is the power?

1) mechanical advantage = 20 N / 200 N = 0.1
2) rope length = 1m / mechanical advantage = 1/0.1 = 10m
3) Work = force * distance traveled and it can be either 200N * 1m or 20N * 10m = 200 J
  

I'll do it rn and then answer

I'm having some difficulty seeing the diagram clearly.but the question says there's a net inward force on the object.so we know right away,  from newton's 2nd law of motion, thatthat baby is accelerating.  it doesn't even matter which way thenet force is pointing.  if there's any net force, then either theobject's speed or else its direction must be changing.
