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