Marie slides a carte of nails across a hardwood floor. The coefficient of kinetic friction between the carte and the floor is 0.120. The crate has a mass of 56.8kg and marie pushes with a horizontal force of 124N. If the 74.4J of total work are done on the crate, how far along the floor does it move?

I'm a lil confused. I know that the equation of kinetic friction is fk=uk * N

But i have problem in determining where i put the variables in the equation.

Im so lost can someone pleaze help me?
