Motion with constant acceleration

The human body can survive an acceleration trauma incident (sudden stop) if the magnitude of the acceleration is less than 250 m/s2. If you are in an automobile accident with an initial speed of 150 km/h (65 mi/h) and you are stopped by an airbag that inflates from the dashboard, over what distance must the airbag stop you from you to survive the crash?

Can somebody help me to solve this exercise?
How do I start?

Completely off topic but at one time we believed that we would not survive any speed over 40mph at any acceleration magnitude.

And now I will shut up.

Yup! :biggrin:

(You know u and v and a, and you want to find s, so you use the equation that doesn't have t. :wink:)

So s = … ? :smile:
