Review I Constan A horizontal spring with spring constant 120 N/m is compressed 20 cm and used to launch a 2.2 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. Part A Use work and energy to find how far the box slides across the rough surface before stopping. Express your answer to two significant figures and Include the appropriate units.
