I can see where I (think) I should go, by the equation you gave and by knowing the actual answer, I can see I find p=E/2c. If this is correct, we know by conservation of momentum that pe=pgamma; how do we know that the energy of the muon is split equally between the electron and photon...

if we treat the muon at rest, Ei=Emuon=Eo=105.7 MeV Ef=Ee+Eγ I know Eγ=hf, but I feel like that's going in the wrong direction for the problem; also I know Ee=γmec2, but without the Eγ, I feel that's a deadend as well.

i do not know how to use four-vectors

Homework Statement Unstable, subatomic particles called muons have a rest energy of 105.7 MeV and a speed of 0.994c. If a muon were to decay and produce an electron and a photon, what would be the momentum of the electron as measured by an observer in the muon's frame? HINT: assume that the...
