What is the average speed a human being can withstand?

Answer 1

humans can withstand any amounts of speed however its the rate of acceleration to that speed that can cause damage to the human body, try and imagine it like this.... when your on a plane you are traveling very fast (I'm not sure how fast) but your body is also traveling at the same rate and so are your organs. however if you quickly got up to the same speed of the plane in a matter of seconds then your organs and your body will have accelerated too fast and you will be crushed so your question is 'what is the average acceleration a human can withstand' well trained astronauts can reach crazy G's of up to 40g's which is 40,000 m/s/s but us untrained humans can usually withstand 17g's without dieing or passing out hope this helps :) im Sarah illusac and 11 years old and i hope to be a rocket scientist one day :)
