Answer: 46.2 G's
Step-by-step explanation:
46.2 G's
The highest G force that a human has survived is 46.2 G's, demonstrated by Air Force Colonel John Stapp, who showed that a human can survive at this level of acceleration for a few seconds. Indycar driver Kenny Bräck survived a split-second deceleration of 214 g during a 220‑mph (354‑km/h) crash on lap 188 of the Chevy 500 at Texas Motor Speedway, USA, on 12 October 20032.
