A skier starts from rest down a 30° slope, and after a vertical drop of 22m, the path temporarly levels out, then drops, at another 20° slope, an additional 31m vertically before leveling out again. What is the skier s speed on the two horizontal stretches if we assume the whole path to be frictionless?
