In 1947, a deceleration sled was built to test the effects of extreme forces on humans and equipment. In this sled, a test pilot undergoes a sudden negative acceleration of about 50.0 times free fall acceleration (g). In 0.181 s, through a distance of 8.05 m, the pilot's speed decreases from 88.9 m/s to 0 m/s. If the pilot's mass is 70.0kg, how much work is done against the pilot's body during deceleration?
