Captain John Stapp of the U.S. Air Force tested the human limits of acceleration by riding on a rocket sled of his own design. His rocket sled, known as the Gee Whiz, had a mass of about 82 kg. What net force would be required to accelerate the 82-kg Gee Whiz and 74-kg Stapp at 540 m/s/s (the highest acceleration tested by Stapp)?
