4. A car moving at 20.0 m/s crashes into a tree. Find the magnitude of the average force acting on a passenger of mass 65 kg in each' of the following cases. (a) The passenger is not wearing a seat belt. He is brought to rest by a collision with the windshield and dashboard that lasts 3.0 ms. (b) The car is equipped with a passenger-side air bag. The force due to the air bag acts for 30 ms, bringing the passenger to rest.
