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…
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 :)
