By applying the conservation of energy and momentum, we can determine the kinetic energy of the decay products. The rest mass of K(0) is 497.6 MeV, and the rest mass of pi(0) is 135.0 MeV. The photon has no rest mass. The solution shows that the kinetic energy of the pi(0) is 0 MeV, while the kinetic energy of the photon is 362.6 MeV, leading to the conclusion that the answer is 0 MeV for pi(0) and 362.6 MeV for the photon."}
