A 1kg box is given a quick push (from rest) up a ramp angled at 30° to the horizontal, using a

spring mechanism of spring constant k = 4000 N/m, initially compressed by 0.1m. The box

slides up the ramp with a coefficient of kinetic friction of 0.4 until it comes to a halt. What

total distance D along the slide does the box travel before it stops? I found the acceleration from the forces and now I am stuck when finding the distance.
