A horizontal spring

A horizontal spring with spring constant 140 N/m is compressed 17 cm and used to launch a 2.8 kg box across a frictionless, horizontal surface. After the box travels some distance, the surface becomes rough. The coefficient of kinetic friction of the box on the surface is 0.15.

 

Use work and energy to find how far the box slides across the rough surface before stopping.
