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?

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

The answer is orbit around nucleus
