At the starting gate of a downhill ski race, a skier pushes with his arms and legs to get as fast a start as possible. The skier leaves the starting gate with an initial speed of 1.60m/s
The race course is made up of both steep and flat sections. A the end of the first flat section, the vertical distance from the skier to the finish line is 80.0m and the skier has a speed of 20.0m/s. At the end of the steepest section, the skier reaches his maximum speed of 33.3m/s (120km/h). The mass of the skier is 68.2kg.
