KE initial must = KE final.

And that's where I'm stuck! (8 x 3) + (4 x -3) = (8 x Vfinal of mass 1) + (4 x Vfinal of mass 2) But how do I combine the equations for conservation of momentum and kinetic energy?

Please clear up this problem... Mass 1 = 8 kg, and v = 3 m/s to the right. Mass 2 = 4 kg, and v = -3 m/s to the left. Both objects are on the same x-plane. Totally elastic collision. Momentum of mass 1 is 24, and momentum of mass 2 is -12. How do I determine final momentum for each...
