# Physics help! A muon and an antimuon are moving in opposite directions with velocities of -0.8 c and 0.8 c, respectively.?

A muon and an antimuon are moving in opposite directions with velocities of -0.8 c and 0.8 c, respectively. When they collide, they can annihilate each other and turn into two photons. Both muon and antimuon have a mass of 105.66 MeV/c2.
