The force is the question, was it horizontal, vertical, or combination.
work=force*distance where force is in the DIRECTION of the distance.

Carla applied a force of 35 N to a wheelbarrow full of bricks and moved it 2.5 m. Which of the following can be determined from this information?
The wheelbarrow supplied 87.5 J of work.
The wheelbarrow has a mechanical advantage of 14.
The wheelbarrow is 7 percent efficient.
The wheelbarrow has 87.5 J of potential energy.
This is just the question, please don't give me the answer. Can someone give me a site where I can figure it out myself?
Thank you!

I just looked at the calculating thing, it was just 35N times 2.5 meters. Does this supply the answer? If so the answer would be A, because the wheelbarrow does not have potential energy. (I.E. Not at the top of a hill.)
