3. A 30-kg skier moves at constant speed down a hill that makes a slope of 15' with the horizontal. i. What is the weight of the skier? ii. What is the net force on the skier? Explain how you can tell. 15 iii. In the space below, draw a free-body diagram for the skier. iii. Based on your free-body diagram, construct a scaled vector sum diagram. iv. Based on your scaled vector sum diagram, what are the magnitudes of each of the forces acting on the skier? Finally, use your results from part iv to calculate the coefficient of friction between the skis and the snow. Show your work
