An extreme skier, starting from rest, coasts down a mountainthat 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 11.4 m beforecoming to the edge of a cliff. Without slowing down, she skis offthe cliff and lands downhill at a point whose vertical distance is4.50 m below the edge. How fast is shegoing just before she lands?
