proton colliding problem

A proton of total energy E collides elastically with a second proton at rest in the laboratory. After the collision the two protons follow trajectories which are disposed symmetrically at angles +/- Φ to the direction of the incident particle. Show that

cos(Φ)= (E-Eo)/(E+3Eo)

Where Eo is the rest mass energy of the proton.
