Question

A 54 kg box is being pushed a distance of 7.0 m across the floor by a force P whose magnitude is 153 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 FRICTIONAL FORCE.
bobpursley
Work = fricionforce*distance
= mu(mg)*distance.
thank you bob.
