What exit speed could a skier reach in the absence of air

Reference no: EM13635467

A professional skier's initial acceleration on fresh snow is 90% of the acceleration expected on a frictionless, inclined plane, the loss being due to friction. Due to air resistance, his acceleration slowly decreases as he picks up speed. The speed record on a mountain in Oregon is 180 kilometers per hour at the bottom of a 22.0 degrees slope that drops 215m. What exit speed could a skier reach in the absence of air resistance and what percentage of this ideal speed is lost to air resistance?
