You are skiing downhill in Lake Tahoe Ski Resort. You start from the height 500 m above the lake level and slide over the run that makes 30° angle with respect to horizontal. Initially your speed is zero. a) Draw a free body diagram that shows all forces that act on the skier. b) What will be your speed at the end of the run if you neglect friction between your skis and the snow? Give the answer in miles per hour. Acceleration of gravity is 9.8 m/s², and 1 mile = 1.609 km
