Question
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.
now I know 35 * 2.5= 87.5
But 35 divided by 2.5 = 14
So Is my answer correct…

Ok, i know I chose C but now that I think about it I'm starting to think it's A...

actually, none of them are correct. The best is A, but that is true only if the 35N applied was in the direction of movement.

Ok, I'll choose A then, THX :)
