How fast do you need to be going when you hit something for your air bags to deploy? The crash forces are equivalent to a head-on collision with an immovable barrier... How fast do you have to be going for the air bags to go off? Air bags are set to deploy when you hit something at a mild 8-14 miles per hour... How fast do you have to be going for the air bags to deploy in a car? You have to be in a collision that is at least 10 mph for the airbags to deploy in...
A typical airbag contains 50.0 g of sodium azide, NaN3. Upon impact, the airbag deploys and inflates within 40 milliseconds to a volume of about 60 L, at a velocity between 150 and 250 mph.The airbag inflates due to the decomposition reaction of NaN3 and fills with nitrogen gas in the following reaction:odium azide (NaN3) can decompose at 300oC to produce sodium metal (Na) and nitrogen gas (N2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN3 to decompose.
