A proton with a speed of 4.20×104 km/s makes an elastic head-on collision with a stationary carbon nucleus. We can look up the masses of both particles.

Which of the following quantities can be calculated from only the known information?

A. The velocity of the proton and carbon nucleus after the collision.
B. The kinetic energy of each of the particles after the collision.
C. The momentum of each of the particles after the collision.
