**Help Again Please -- Box sliding on a floor**

## Homework Statement

If the friction coefficient between the box and the floor is .23, and the box has a mass of 12 kg, and the magnitude of all four forces is 10 N, what is the change in kinetic energy of the box after it has traveled a distance of 4 meters to the east?

## Homework Equations

Friction force =(mu)(normal force)

w total= Kinetic final - Kinetic Initial

W total= force * distance

kinetic energy is 1/2mv^2

## The Attempt at a Solution

The attempt was calculating the friction force, calculating the applied force, and then subtracting the friction force from the applied force.
