A stationary particle of rest mass [tex]2m_{0}[/tex] is hit by a particle of rest mass [tex]m_{0}[/tex] and kinetic energy [tex]2m_{0} c^{2}[/tex]. I must find the rest mass of the composite particle afterward.

2. Relevant equations

Conservation of momentum and energy.

3. The attempt at a solution

I worked problems with identical mass and velocity, but I don't exactly know what to do with this particular problem. I'm still having trouble understanding the explanation my book provided, so I was hoping someone can give me a more lucid elaboration of this whole phenomenon.
