For many years Colonel John P. Stapp, USAF, held the world's land speed record. He participated in studying whether a jet pilot could survive emergency ejection. On March 19, 1954, he rode a rocket-propelled sled that moved down a track at a speed of 632 mi/h. He and the sled were safely brought to rest in 1.40 s. (a) Determine the (negative) acceleration he experienced, converting your answer into metric units. (b) Determine the distance he traveled during this negative acceleration, converting your answer into metric units.
