Part A A horizontal spring with spring constant 130 N/m is compressed 15 cm and used to launch a 2.7 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. Express your answer to two significant figures and include the appropriate units. H 1 = Value cm 0 ?
