A snowboarder starts from rest on an inclined planar snow surface and gives herself a tiny push to start sliding down the hill. The coefficient of kinetic friction between her snowboard and the snow is 0.08. She notices that she travels 30.11 m horizontally and 37.18 m vertically (downward) before whizzing by a marker flag. How fast is she traveling as she passes the flag?

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 12.7 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 3.30 m below the edge. How fast is she going just before she...

A 55.8 kg person skis down a 10 m tall hill. They start from rest at the top of the hill, but friction and air resistance both affect the skiers motion. If friction and air resistance have the effect of dissipating 1,027 J of energy away from the skier over the entire length of the hill, how fast are they traveling when they reach the bottom? Report your answer in meters per second, rounded to one decimal place
