A proton (mass 1 u) moving at 6.90 X 106 m/s collides
elastically and head-on with a second particle moving in the opposite
direction at 2.80 X 106 m/s. After the collision, the proton
is moving opposite its initial direction at 8.62 X 106 m/s.
Find the mass and final velocity of the second particle.
