A pion has a rest energy of 135MeV. It decays into two gamma rays, bursts of electromagnetic radiation that travel at the speed of light. A pion moving through the laboratory at v=0.98c decays into two gamma rays of equal energies, making equal angles with the direction of motion. Find the angle (theta) and the energies of the two gamma rays. (HInt: Gamma rays are electromagnetic radiation with E=pc).
