Northrop aircraft developed and built a deceleration sled to test the effects of the extreme forces on humans and equipment. In this sled a test pilot with the mss of 70 kg undergoes a sudden negative acceleration of 490 m/s. This deceleration occurs over a distance of 8.05 m. How much work is done against the pilots body during the deceleration?
