An extreme skier, starting from rest, coasts down a mountain slopethat makes an angle 25.0° with the horizontal. The coefficientof kinetic friction between her skis and the snow is 0.200. Shecoasts for a distance of 11.0 m beforecoming to the edge of a cliff. Without slowing down, she skis offthe cliff and lands downhill at a point whose vertical distance is3.10 m below the edge.
How fast is she going just before she lands?
