A skier starts down a 26 slope. After a vertical drop of 28 m, the slope temporarily levels out and then drops at 19 an additional 39 m vertically before leveling out again. The coefficient of kinetic friction on both slopes is 0.11, the level stretches is frictionless.
What is the skier's speed on the higher level stretch?
