How much work is accomplished when a force of 250 N pushes a box across the floor for a distance of 50 meters?

mote1985 [20]

We use the work formula to solve for the unknown in the problem. The formula for work is expressed as the product of the net force and the distance traveled by the object. We were given both the force and the distance so we can solve work directly.

Work = 250 N x 50 m = 12500 J

Thus, the answer is C.
