Physics

A block of mass m = 2.5 kg is attached to a spring withspring constant k = 640 N/m. It is initially at rest on aninclined plane that is at an angle of θ = 27° with respectto the horizontal, and the coefficient of kinetic friction betweenthe block and the plane is μk = 0.11. In theinitial position, where the spring is compressed by a distance ofd = 0.19 m, the mass is at its lowest position and thespring is compressed the maximum amount. Take the initialgravitational energy of the block as zero.

Question:

If the spring pushes the block up the incline, whatdistance, L in meters, will the block travel before comingto rest? The spring remains attached to both the block and thefixed wall throughout its motion?
