meatmissile 0 #1 October 17, 2003 Is roughly the amount of power the average person will dissipate into the athmosphere in freefall. I wonder where it all goes. So, Bill - you are still a waster of energy, even if only in brief spurts -- ZZZzzzz.... Quote Share this post Link to post Share on other sites
dterrick 0 #2 October 17, 2003 The physics, please? You talkin about plane juice per jumper? Anyone out there invent a solar powered jumpship yet? Dave Quote Share this post Link to post Share on other sites
Push 0 #3 October 17, 2003 QuoteI wonder where it all goes. Sound and heat. -- Toggle Whippin' Yahoo Skydiving is easy. All you have to do is relax while plummetting at 120 mph from 10,000' with nothing but some nylon and webbing to save you. Quote Share this post Link to post Share on other sites
JeffD 0 #4 October 17, 2003 so how much energy does it take to get the jumper up there? Quote Share this post Link to post Share on other sites
meatmissile 0 #5 October 17, 2003 QuoteThe physics, please? Power(watt)=Force(Newton)xSpeed(meters/second) Now, for a jumper + equipment of 70 kilograms, you would require (at terminal velocity), a balancing force of roughly 700N, assuming gravity acceleration to be approximately 10 meters/second (~9.81, close enough). Taking the jumper's speed as 180km/h or 180000/(60^2) = 50m/s So, Power = (700 x 50) = 35000Watt = 35 Kilowatt OK, so I said 40. It could be even higher for a heavier person in a head-down or track. Happy? -- ZZZzzzz.... Quote Share this post Link to post Share on other sites

billvon 3,120 #7 October 17, 2003 >So, Bill - you are still a waster of energy, even if only in brief spurts But in a wingsuit, I only dissipate about 22 kilowatts during descent! Quote Share this post Link to post Share on other sites
