In the figure, a 3.8 kg block slides along a track from one level to a higher level after passing through an intermediate valley (frictionless). 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 v0 = 6.9 m/s, the height difference is h = 1.2 m, and μk = 0.649. Find d.
i've already found that energy transferred to thermal energy is 45.771 J, the normal force = 37.24 and the KE frictional force = 24.168 J but I'm not sure what to do with these numbers.
