use conservation of momentum.
Ma*Va+Mb*Vb=Ma*Va' + Mb*Vb'
28(Ma-Mb)=
well, at this point, you have two unknowns, and you have to stop. You cannot use conservation of energy, you have no basis to assume it was an elastic collision.
Two cars have a head on collision. Both are traveling at 28 m/s toward each othe. Car A has a mass of 700 kg and car B has a mass of 904kg. What is car B velocity after the impact?
