Two cars have a headon collision. Both were traveling at 28 m/s toward each other. Car A has a mass of 700 kg and car B has a mass of 904 kg. After the impact, what is car B's velocity?

Again,this cannot be solved without some assumption on energy, and in a head on collision, conservation of mechanical energy is out of the question. If you have other thoughts, I would like to hear them.
