Calculating the Maximum Kinetic Energy of pions

  • #1

Homework Statement


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

Homework Equations


K+---> π0 + π- + π+

The Attempt at a Solution



494-(140+140+135) = 79MeV

In the book it says answer is 74MeV[/B]

Hello kashif, :welcome:

There is something wrong with your relevant equation: what about charge in your decay mode ?
