determining the work done

Question

A box with a mass of 3.72 kg is sliding along a horizontal surface at constant velocity. It is pulled by a horizontal force and the coefficient of kinetic friction between the box and the surface is 0.25.

What is the work done, in joules, by the pulling force as the box moves a distance of 0.71 m?

What is the work done, in joules, by the force of friction on the box as the box moves a distance of 0.71 m?

What is the work done, in joules, by the net force on the box?
