Question

Two protons approach each other with different speeds.
(a) Will the magnitude of the total momentum of the two-proton system be (1) greater than the magnitude of the momentum of either proton, (2) equal to the difference between the magnitudes of momenta of the two protons, or (3) equal to the sum of the magnitudes of momenta of the two protons? Why?
(b) If the speeds of the two protons are 340 m/s and 450 m/s, respectively, what is the total momentum of the two-proton system?
