When a positron and an electron meet, they are both annihilated into pure energy. Calculate how much energy (in MeV) is released in this reaction assuming that each particle is moving at 50% the speed of light. For this question use the classical definition of kinetic energy.

Hint- A positron has the same mass as an electron, and don't forget to calculate the energy from each particle. 1 J = 6.242 x 1012 MeV
