A pion at rest ([tex]m_pi = 273m_e[/tex]) decays to a muon (mass = 207[tex]m_e[/tex] and an antineutrino (mass = 0). Find the kinetic energy of the muon and the energy of the antineutrino in electron volts.(adsbygoogle = window.adsbygoogle || []).push({});

How am I supposed to start this problem? ANy help would be great...thx!
