a particle's rest mass is 1.25 M0c^2, decays into two identical paricles of mass .45M0 each.
a) calculate the possible velocities of the mother particle.
b) what would be the energy of the mother particle in a reference moving at a speed of 0.6c in the smae direction as the mother particle?
c) obtain the speeds of the two daughter particles if their velocities are along the direction of motion of the parent particle. use m0c^2=1E4 MeV.
