Kinetic energy of two protons to create a meson?

  1. Mar 12, 2012 #1
    1. The problem statement, all variables and given/known data
    This one stumped me a little
    Two protons are heading toward each other with equal speeds.
    What minimum kinetic energy must each have if a ∏2 meson is to be created in the process?

    2. Relevant equations
    E=mc2
    p+p→p+p+∏2
    E=Ek-mc2 ? not sure if I got this right or even useful

    3. The attempt at a solution

    E=mc2
    =135MeV
    =135x106x1.6x10-19
    =2.16x10-11

    actually I worked it out, it was correct, they just wanted it in MeV
