X-Original-Date: Sat, 4 Aug 2007 11:47:10 -0400 X-Original-To: Lancair List X-Mailer: Apple Mail (2.752.3) Matt, I believe that the terminal velocity (TV) for an arbitrarily shaped object including a human body is about 120 mph. This speed is also the speed at which frictional forces switch from linear to squared. In order to go faster, the sky diver has to put his arms behind him and go straight down headfirst. At this time his TV can reach up to 160 mph or possibly 175 mph. Lorn > From: "Matt Hapgood" > Date: August 4, 2007 1:06:54 AM GMT-04:00 > > Isn't terminal velocity for a falling human about 175 mph?
