The main purpose of an air bag is to stop a passenger during a car accident in a greater amount of time than if the air bag were not present. For example, consider a 55 kg person traveling at 29 m/s (about 65 mph). Use impulse and momentum to calculate how many newtons of force would be required to stop the person in 0.035 s, 0.070 s, and 0.35 s. Note how the force changes with increased time. (Enter the magnitudes.)
