First order equations

Get inspired:

On October 14, 2012, Felix Baumgartner skydived from a heigh of 39 km (24 mi), reaching an estimated speed of 1,342 km/hr (834 mph). He descended in free-fall for 4 minutes and 20 seconds. You can watch the footage, which is impressive and scary all at once. At about 2:30 into the video, he starts getting out of his capsule. The camera shot at 3:00 is terrifying. He jumps at 3:34. He deploys his parachute at 7:55. He lands at 12:37. What does this have to do with differential equations? Falling objects are one of the most fundamental problems modeled with first order differential equations.
