In October 2012 skydiver Felix Baumgartner jumped from a balloon nearly 24 miles above the surface of Earth, reaching an estimated maximum speed of 834MPH on his descent; this velocity is in excess of the speed of sound (768 MPH). However, the typical maximum speed reached by skydivers jumping out of a plane at an elevation of 13,000 feet is only approximately 210MPH. Explain why Felix was able to break the sound barrier on his descent from the balloon. One of more of the following equations may be helpful: g(sg)=dp2mf3150(1mf)umf+dpmf31.75gumf2LP=dp21503(1)2u0dp1.75g3(1)u02ut=18(sg)gdp2
