SUMMARY
The maximum kinetic energy of pions resulting from the decay of a kaon at rest is calculated using the rest energy values provided. The rest energies for pions are π- 140 MeV, π0 135 MeV, and π+ 140 MeV, while the rest energies for kaons are K- 494 MeV, K0 498 MeV, and K+ 494 MeV. The initial calculation of 79 MeV is incorrect; the correct maximum kinetic energy is 74 MeV as stated in the reference book. The discrepancy arises from not accounting for charge conservation in the decay equation K+ → π0 + π- + π+.
