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…

  2. 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.
