Okay that makes sense, I did not realize that was where the E = pc formula was derived from, for some reason I thought it only held for photons. I believe I can solve the problem from here, thank you for all your help.

well if it is not zero than it cannot be p= ϒmv. Could we treat it like a photon and use E=pc?

Oh because the momentum is conserved? So the final momentum p would be equal to the initial momentum of the system, since the proton was at rest and the electron is essentially massless is the momentum 0? So I would just plug in the E I found earlier and 0 into the equation E2 = p2*c2 + m2*c4...

well doesn't p=ϒmv?

So I know that since we are ignoring the mass of the electron, and the proton starts at rest, the proton has no KE and the electron has no rest energy. So the initial total energy of the system would be rest energy of proton + KE of electron = 2GeV + .938GeV = 2.938 GeV and since energy is...
