PLS ANSWER ASAP

A 3-kg block has a speed of v=8.5 m/s at point O as it travels along a rough incline OA with
Mk = 0.25. It then hits a spring with k=500 N/m at point A and eventually comes to a temporary
stop as it reaches its highest point. Let x be the deformation of the spring when the block
reaches a temporary stop.
