In the decay of a pion at rest into a muon and a neutrino, the total energy before the decay (the rest mass energy of the pion) must equal the total energy after the decay (the sum of the kinetic energies of the muon and the neutrino, plus their rest mass Show more…

If a muon at rest decays into an electron and two neutrinos, what is the total kinetic energy of the decay products? Assume that the neutrinos have zero rest mass. The electron and muon rest masses are 0.511 and 105.7 MeV/c^2, respectively. A) 1.022 MeV B) 211.4 MeV C) 106.2 MeV D) 105.2 MeV E) 105.7 MeV

A π meson (rest mass 139.6 MeV) decays at rest into a μ meson (rest mass 106 MeV) and a neutrino. The kinetic energy of the μ meson is always equal to 4.40 MeV.

A muon has a rest mass energy of $105.7 \mathrm{MeV}$, and it decays into an electron and a massless particle. (a) If all the lost mass is converted into the electron's kinetic energy, find $\gamma$ for the electron. (b) What is the electron's velocity?
