A horizontal spring with spring constant 150 N/m is compressed 17 cm and used to launch a 2.9 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.

A box with a mass of 1.386 kilograms collides head-on with a spring constant of 1.26 m*N. When the box stopped, the spring was compressed by 25.05 centimeters. The kinetic friction coefficient between the box and the floor is 0.484 and the gravitational acceleration is 9.8 m/s2. At this point, obtain the speed (m/s) of the box just before it comes into contact with the spring.
