In the figure, a 4.2 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 7.3 m/s, the height difference is h = 0.97 m, and k = 0.558. Find d. Number i Units d = 0- h Mk
