## Homework Statement

A 40.0kg box initially at rest is pushed 5.00m along a rough, horizontal floor with a constant applied horizontal force of 130N. If the coefficient of friction between box and floor is 0.300, find the work done by the normal force?

## Homework Equations

W=F*d

## The Attempt at a Solution

The answer is 0N, however i got 1260(which i know does not seem logically correct).

So can someone explain to me why does work done by the normal force equal to 0N.
