Question

A small block slides along a track from one level to a higher level, by moving through an intermediate valley (see Figure). The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. Assume that the block's initial speed is 10 m/s, the height difference h is 3.3 m, and μk is 0.87. Find the distance d that the block travels on the higher level before stopping.
