14. The human body can survive an acceleration trauma incident (sudden stop) if the magnitude of the acceleration is less than 2.5m/s2. If you are in an automobile accident with an initial speed of 105km/h and you are stopped by an airbag that inflates from the dashboard, over what distance must the airbag stop you for you to survive the crash?
