An electron moving at a speed of 0.97c collides head-on with apositron also moving at 0.97c. Determine the energy and momentum ofeach photon produced in the process. The rest mass of an electron(and that of a positron) is 0.511 MeV/C*C.

Need some help on this one.. thanks a lot!

In an antimatter warp drive engine, an electron traveling at aspeed of 0.410c meets an antielectron (i.e., a positron) head on,traveling at a speed of 0.740c. They annihilate each other, andproduce two gamma rays. What is the total energy of the resultinggamma rays? The electron and the positron have identical mass, of9.11Ã10-31 kg, or 0.511 MeV/c2.

Answer in MeV

The mass of an electron is 9.11 x 10^-31 kg. If the de Broglie wavelength for an electron in a hydrogen atom is 3.31 x 10^-10 m, how fast is the electron moving relative to the speed of light? The speed of light is 3.00 x 10⁸ m/s.
