During the late 1940's, Colonel John Paul Stapp was a pioneer in studying the effects of acceleration and deceleration on the humanbody. He made multiple runs strapped to a rocket sled that quickly accelerated him to high speeds along a straight track (see figure).His research led to improvements in restraining harnesses and seatbelts for pilots and automobile occupants. During his final run, hereached a maximum speed of 632 mph. When the sled's braking system brought it to rest, Colonel Stapp experienced a deceleration ofmagnitude 46.2g, or 46.2 times the acceleration of gravity at the Earth's surface. Although he survived, he did sustain injuries, such as afractured wrist, broken ribs, and bleeding in his eyes. Calculate how long it took to bring the rocket sled to rest. Assume thedeceleration was constant during the braking period.NumberiUnitsJohn Paul Stapp, Imagetaken from https://commons.wikimedia.org/wiki/File:Stapp_hits_the_brakes,_hard.gifKeystone/Stringer/Hulton Archive/GettyImages
