When analyzing Felix Baumgartner's dive for homework, you at one point addressed the question of how he was able to slow down in the course of his fall. There are actually several different ways his speed was reduced -- some under his control and some not -- and given our discussion of air resistance in class, you should have a good grasp of at least some of the ideas at this point.
Discuss at least two things that occurred to slow Felix down -- if at all possible, try to discuss one that was under his control and one that was not.
