2 Situations.(adsbygoogle = window.adsbygoogle || []).push({});

One: Two identical cars crash head on (inelasticly) @ v miles per hour each (in opposide directions of course).

Two: A car identical to those two cards crashes (inelasticly) @ v miles per hour into a brick wall (ie. solid and unmovable... although I have seen pics of a car that just went through a brick wall...).

Wich of the two situations results in the greatest impact force.

Which answer?

The forces are the same in both.

Hitting the other car (One>Two).

P=momentum

J=impulse

I figure F (impluse; whatever) =delta(P) right? So in the first situation delta P is greater since they have opposing velocites (-P and P).

But if you do P+J=0 then J=P in both cases right?

I'm pretty confused; what's right and why? HElps mes!
