    This question was the difference between a 13 and a 14... THIS stupid freaking question :D

    Is it me or is this a totally loaded question? Which involves more work? I need not put any force on the wire for it to go from A to B.

    So 0 x distance = 0....

    To lift it I must put a Force on the rope

    F x distance =/= 0

    Is this ambiguity on their part or am I just being ridiculous?

    MDApps:
    Work is F*d. Draw a free body diagram and you will see 2 forces, force "F" and mg. Alternatively, it is simpler to just use conservation of energy.

    there are no non-conservative forces acting on the block, the pully thrown in there is a red herring in my view. E=E' mgh=mgh the only forces on the block before and after.
