The main thing to remember when doing calculations with the two cars is that one car is doing +50km/h , the other one is doing -50km/h. This therfore means that if you add the velocities, you get 0.

so.... hitting a brick wall at 50km/h will be the same as hitting a (identical) car travelling in the opposite direction, going 50km'h.

common sense also shows this... you are going from 50km/h to 0km/h in a set time, being the time taken for the crumple zone to well... crumple. this is regardless of what you hit. if you hit another car, the other cars crumple zone doesn't "really" affect your cars, as it has its own car to take care of.

no, no, no
if you do actually use common sense, you will find that, firstly, hitting a stationary car (assuming it is the same as yours) at 50km/h will do much less damage than colliding with the same car, where you are both doing 50km/h, and secondly, another car's crumple zone will actually affect the force exerted on you, as the object you're hitting will absorb some of the energy into crumpling the metal

man, this stuff is all so obvious to me, i cant see how some of you guys are getting it so wrong! Confused
