Obtain how fast is she going just before she lands

An extreme skier, starting from rest, coasts down a mountain slope that makes an angle of 25.0o with the horizontal. The coefficient of kinetic friction between her skis and the snow is 0.200. She coasts down a distance of 10.4 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 3.50 m below the edge. How fast is she going just before she lands? (HINT: Use energy considerations.)
