how far does a human fall in 3 seconds
Equations for a falling body Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth (i.e., face down) free-fall position is about 195 km/h (122 mph or 54 m/s). This velocity is the asymptotic limiting value of the acceleration process, because the effective forces on the body balance each other more and more closely as the terminal velocity is approached. In this example, a speed of 50% of terminal velocity is reached after only about 3 seconds, while it takes 8 seconds to reach 90%, 15 seconds to reach 99% and so on.
Red Bull Stratos Red Bull Stratos was a space diving project involving Austrian skydiver Felix Baumgartner. On 14 October 2012, Baumgartner flew approximately 39 kilometres (24Â mi)[1][2][3] into the stratosphere over New Mexico, United States, in a helium balloon before free falling in a pressure suit and then parachuting to Earth.[4] The total jump, from leaving the capsule to landing on the ground, lasted approximately ten minutes.[1] While the free fall was initially expected to last between five and six minutes,[5] Baumgartner deployed his parachute after 4 minutes and 19 seconds.[1]
