WHOLE QUESTION: A car is stopped for a traffic signal. when the light turns green, the car accelerates, increasing its speed from 0 to 5.20m/s in 0.832s.
What are the magnitudes of the linear impulse and the average total force experienced by a 70.0-kg passenger in the car during the time the car accelerates?
Linear impulse=change in momentum=mass x change in velocity=70.0 x 5.20=364 Ns
Average force = change in momentum /time=364 /0.832=437.5 N
