Question: Prepare vt and Ft graphs of Stapps trip, and compute the g forces he experienced in the course of acceleration and deceleration. In the 1950s

Prepare v–t and F–t graphs of Stapp’s trip, and compute the g forces he experienced in the course of acceleration and deceleration.

5.7 279 m/s Fg t 0,0 -9.5 0,0 5.0 s 3.0 s 5.0 s 3.0 s


In the 1950s when Air Force Colonel John Paul Stapp volunteered to ride a rocket sled to test the resistance of the human body to g forces. The sled accelerated from 0 to 625 miles per hour in 5.0 seconds. Then the sled hit a water brake and decelerated in 3.0 seconds to a standstill. Assume that Stapp was rigidly strapped into the sled and that he had a mass of 75 kg.
