A person with a mass of 55.0 kg skis down an incline of 40 degrees from the horizontal. If the kinetic coefficient between her skis and the slope is 0.14, what will be her accelaration down the slope? What will be her speed after skiing 8.0 m down the slope if she was at rest when she began her descent? If after reaching the bottom she wishes to climb a slope of 20 degrees at constant velocity, what force must she generate to propel herself up the slope? Assume friction does not change. Also, draw correct vector diagrams that clearly show all forces.(adsbygoogle = window.adsbygoogle || []).push({});

I am unsure how to solve this problem because I do not know how the incline effects forces. I know that on a flat surface there would be a weight force going down and a normal force going straight up and that both would be equal to mg. i also know that there would be a frictional force of kinetic coefficient* mg that would be going horizontally from the back of the skier however, I do not know how all this changes when you are on an incline.
