A box is resting on an incline (40 degree angle incline) and this incline has a coefficient of kinetic friction of .3. The box has a mass of 10kg   At the base of the incline is a spring. This spring is initally compressed .2m and has a spring constant of 2 kN/m.   The box starts 2m up the incline from the spring   If the box is slid down the incline, how far is the spring compressed when the box stops moving?
