## Homework Statement

A relativistic particle with mass at rest M0 and velocity v hits another particle with mass at rest M1. the collision is perfectly inelastic. How can I calculate the mass at rest of the new particles after the collision?

Easiest way to do this is using 4-momentum, [itex]p_\mu=(\frac{E}{c},\vec{p})[/itex]. Note that 4-momentum is conserved and [itex]p^\mu p_\mu=-m^2 c^2[/itex] is invariant.
