Question: 

For the decay $\Lambda^0 \rightarrow$ p + $\pi^-$, calculate

  1. the Q-value (energy released), and
  2. the kinetic energy of the p and $\pi^-$, assuming the decays from rest. (Use relativistic formulas.)

Quick Answer: 
  1. $37.8 \textrm{ MeV}$
  2. $KE_p = 5.4 \textrm{ MeV, } KE_{\pi^-} = 32 \textrm{ MeV}$
