An extreme skier, starting from rest, coasts down a mountain slope that makes an angle 25.0 degrees with the horizontal. The coeffecient of kinetic friction between the skier and the snow is 0.200. She coasts for a distance of 13.7 m before coming to the edge of the cliff. Without slowing down, she skies off the cliff and lands downhill at a point whose vertical distance is 3.10 m below the edge. How fast is she going just before she lands?
