The (2S) meson is an unstable particle with rest energy 3686 MeV. One way in which a (2S) can decay is into a positive K meson ( K+) and a negative K meson ( K), each with rest energy 495 MeV. Assume the (2S) is at rest before it decays. Find (a) the kinetic energy in MeV, (b) the Lorentz factor , and (c) the speed (in terms of c) of each K meson.
