The coefficient of kinetic friction between a suitcase and the floor is 0.23. If the suitcase has a mass of 70.0 kg, how far can it be pushed across the level floor with 530 J of work?

Use Work done = force * distance to solve for distance.
force = μmg (assuming the suitcase is already in motion).
Work done = 530 J.
