An extreme skier, starting from rest, coasts down a mountain that makes an angle of 34.2 ° with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.156. She coasts for a distance of 17.0 m before coming to the edge of a cliff. Without slowing down, she skis off the cliff and lands downhill at a point whose vertical distance is 3.93 m below the edge. How fast is she going just before she lands?
