here is my question and my solution, id like to see where i have gone wrong and how to rectify it:(adsbygoogle = window.adsbygoogle || []).push({});

A particle of mass M, at rest, decays into two smaller particles, masses m1 and m2. What are their energies and 4-momenta (given: [tex] \sqrt{p^2 + m_1^2c^2}+\sqrt{p^2 + m_2^2c^2}=Mc[/tex] [tex]E_1 = \sqrt {m_1^1c^4 + p^2c^2} [/tex] [tex] E_2=\sqrt{m_2^2c^4+p^2c^2}[/tex]? then the part i am working on: solve the problem again for m2=0. solve the equations for p and e1, and take the limit m1 -> 0.

i find it kind of ambiguous, but to clarify, is the correct answer obtained by using the equation for Mc and subbing m2=0 in there, then using the two equations you then have to solve for E2?
