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 (see figure below).Explanation / Answer
1mi/h=0.4407 m/s
632mi/h=278.52m/s
a)a=(0-278.52)/1.4=-198.4m/s2
b)S=(v^2-u^2)/2a =(0-278.52^2)/(2*-198.4)=
