If you are in an automobile accident with an initial speed of 120 and are stopped by an airbag , over what distance must the airbag stop you for you to survive the crash???:confused:

And if the acceleration is less that 250!

120 what? 250 what?

Please clarify your question. 250 what? Meters per second squared? When you are in this accident at "120" - is this the velocity of the car at the instant of impact, and if so is it MPH? You seem to be asking what distance you cover when decelerating from 120 to 0 with a deceleration of 250 - is that right?
