Colonel John Stapp led the U. S. Air Force Aero Medical Laboratory’s research into the effects of high accelerations on the human body. On Stapp’s final run, he rode a rocket-propelled sled that reached a speed of 284.4 m/s (632 mph) and then stopped with the aid of water brakes in 1.2 seconds. Stapp was barely conscious and lost his vision for several days, but recovered. Determine his acceleration while stopping and the distance he travelled while stopping.
