## Homework Statement

A woman pushes a lawn mower(25-kg) with a force of 400 N at an angle 45 degrees below the horizontal for a displacement of 12 meters. The coefficient of friction between the lawn and the mower is 0.1. The answer is -634 J but I get a different answer.

## Homework Equations

W = F (d)

## The Attempt at a Solution

W = -(coefficient of friction) (mg) (12 m)

W = - 0.1 * 25 * 9.8 * 12

W = -294J
