spring question.png A 2.50 kg mass is sliding along a rough  level, surface of coefficient of kinetic friction of 0.350 between the mass and the surface, when it encounters a spring of spring of spring constant 125 N/m.  If the mass is traveling at 1.20 m/s when it contacts the spring determine by how much the spring compresses in stopping the mass.
