An extreme skier, starting from rest, coasts down a mountain slope that makes an angle of 25.0° with the horizontal. the coefficient of kinetic friction between her skis and the snow is 0.200. she coasts down a distance of 8.7 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 4.20 m below the edge. how fast is she going just before she lands
