The problem is to Use the rest energy values in table 1 to calculate the maximum kinetic energy of the pions assuming the kaon is at rest before it decays.
Rest Energies of pions are π- 140, π0 135 and π+ 140.
Rest energies of kaons K- 494, K0 498 K+ 494
K+---> π0 + π- + π+
The Attempt at a Solution
494-(140+140+135) = 79MeV
In the book it says answer is 74MeV[/B]
