Unformatted text preview: below the horizontal. There is a sticky 0.20 coefficient of friction between the slope and the skis. The finishline flag is 200m from the starting position. Use a gravitational constant is 10 m/s 2 . a. Draw the gravitational force acting on the skier? Which component does work? What is the work done by gravity? Is it positive Work or negative Work? Why? b. Draw the frictional force on the skier? What is the work done by friction? Is it positive Work or negative Work? Why? c. What is the work done by the normal force? Why? d. What is the total work done? e. What is the initial kinetic energy? What is the final kinetic energy? f. Determine the skier's speed as she reaches the finish line. g. REDO problem using NEWTON'S SECOND LAW. (use separate page) 41.4 200 m...
