Question

find the magnitude of the horizontal force ,in N , required to push an object a distance of 2.00 meters if the force did 0.0430 j of work to perform the task .

Answer 1

Work = (force) x (distance)

You have given the work and the distance,
so we can write:
0.0430 J = (force) x (2 meters)

Divide each side by 2: Force = (0.0430 J) / (2 meters) = 0.0215 Newton

That's about 0.077 ounce of force.
