Help Again Please -- Box sliding on a floor 1. The problem statement, all variables and given/known data 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? 2. Relevant equations Friction force =(mu)(normal force) w total= Kinetic final - Kinetic Initial W total= force * distance kinetic energy is 1/2mv^2 3. 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.
