Question 2. [25 points] For the winter holiday you decide to go sledding in Wisconsin. You find a good hill that has a height of 20 meters from the ground. The path then takes you over a smaller hill with a height of 5 meters.. The hills are pretty icy such that friction is negligible. After the second hill you finally reach the ground which is 20 m 5 m not as icy and has some friction. You estimate that the coefficient of kinetic friction on the ground is about 0.2. You estimate that the combined mass of you and the sled are 120 kg. A. [8 points] Find your speed when you are at the top of the second hill. Assume your speed is such that the sled does not come off the hill. Show all work. B. [8 points] Find your speed at the bottom of the hill (i.e at the ground level.) Show all work. C. When the sled gets to the ground you experience some friction, bringing the sled to rest. a. [5 points] Sketch a free body diagram for the sled while it is slowing down on the ground. b. [4 points] At what distance does the sled come to rest?
