Colonel John P. Stapp, USAF, 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 (see figure below). He and the sled were safely brought to rest in 1.40 s. (a) Determine in SI units the negative acceleration he experienced. (m/s2) (b) Determine in SI units the distance he traveled during this negative acceleration. (m)
