The coefficient of kinetic friction between a suitcase and the floor is 2.14. If the suitcase has a mass of 71.5 kg, how far can it be pushed across the level floor with 570 J of work?

(Friction force) x (distance) = 570 J
The friction force is 2.14 M*g
You know what M and g are.
Solve for the distance
