A 60 kg snowboarder (including equipment) heads down a ski hill starting at a height of 100 m, from an initial speed of 4.5 m/s above the flat surface at the bottom.  Use the Law of Conservation of Energy to determine the speed she could attain by the time she hits the flat (at the bottom of the hill).  If she only reaches a speed of 90 km/h what was the energy lost to friction?
