# What is the work done by each force on a box being pushed?

Not what you're looking for?

A 48 kg box is being pushed a distance of 7.0 m across the floor by a force P whose magnitude is 143 N. The force P is parallel to the displacement of the box. The coefficient of kinetic friction is 0.25. Determine the work done on the box by each of the four forces that act on the box. Be sure to include the proper plus or minus sign for the work done by each force.

##### Solution Summary

This solution shows how to determine the work done by the four forces: applied force, frictional force, normal force and gravity. This solution shows calculations and answers in an attached Word document.
