A proton, moving with a velocity of v1i collides elastically with another proton that is initially at rest. One proton has three times the speed of the other after the collision. How would I find the speed of each proton after the collision in terms of vi and their velocity vectors after the collision?(adsbygoogle = window.adsbygoogle || []).push({});

I understand that momentum is conserved, but i see how to apply it.

Any help would greatly be appreciated.
