Dr. John Paul Stapp was U.S. Air Force officer who studied the effect of extreme acceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating form rest to a top speed of 282 m/s (1015 km/h) in 5.00 s and was brought jarringly back to rest an only 1.40 s. Calculate his (a) acceleration in his direction of motion and (b) acceleration opposite to his direction of motion. Express each in multiples of g(9.80m/s2) by taking its ratio to the acceleration of gravity.
