A pi meson of rest energy 139.6 MeV moving at a speed of 0.906c collides with and sticks to a proton of rest energy 938.3 MeV that is at rest.
(a) Find the total relativistic enrgy of the resulting composite particle.
(b) Find the total linear momentum of the composite particle.
(c) Using the results of (a) and (b), find the rest energy of the composite particle.
