The variation of momentum (= the impulse) of the car during the impact is
[tex]\Delta p = F \Delta t[/tex]
[tex]\Delta p [/tex] does not change whether the car has an airbag or not, because
[tex]\Delta p = m\Delta v[/tex]
and 1) the mass of the car is always the same 2) the change in velocity of the car is always the same,
so if [tex]\Delta p[/tex] is constant and F is reduced by a factor 110, then [tex]\Delta t[/tex] (the duration of the collision) must be increased by a factor 110 with the airbag.
