A skier travels down the trail as shown below. The slope is inclined at an angle of 22 and the coefficient of kinetic friction is 0.2. a) Draw the free body diagram of the skier. [2 marks] b) Using Newton's Laws of motion, determine the speed of the skier when he moved a distance, s = 21 m, [4 marks] c) Using energy conservation law, recalculate his speed when s = 21 m. marks] [4 All vector diagrams must be drawn using ruler. (No marks will be provided for free hand drawing) D
