A K0 meson (mass 497.61 MeV/c2) decays to a π+, π− pair with a mean lifetime of 0.89 ×-10s. Suppose the K0 has a kinetic energy of 276 MeV when it decays, and that the two π mesons emerge at equal angles to the original K0 direction. Calculate the kinetic energy of each π meson and the opening angle between them. The mass of a π meson is 139.57 MeV/c2
