Hiya. The problem i'm trying to solve is this:
To solve the problem of what speeds the two cars have after an ELASTIC collision, i used simultaneous equations. My process was:
From my workings, i seem to have found that if the masses of the two vehicles are equal, then in an elastic collision; the speeds afterwards of the two vehicles will just swap. e.g.
Will that be the same for all collisions where the mass is the same and the collision is elastic?
