Agovernment agency estimated that air bags have saved over 14,000 lives as of april 2004 in the united states. (they also stated that air bags have been confirmed as killing 242 people, and they stress that seat belts are estimated to save 11,000 lives a year.) assume that a car crashes and has come to a stop when the air bag inflates, causing a 75.0 kg person moving forward at 15.0 m/s to stop moving in 0.0250 seconds. (a) what is the magnitude of the person's impulse? (b) what is the magnitude of the average force the airbag exerts on the person?
