Elastic collision between proton and carbon atom at 3.50×10⁷ m/s

[Justin M]

A proton is traveling to the right at 3.50×107 m/s. It has a head-on perfectly elastic collision with a carbon atom. The mass of the carbon atom is 12 times the mass of the proton. What is the magnitude of proton speed after the collision? What is the magnitude of carbon atom speed after the collision?
