(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Tow protons of equal energy collide head on and the result is

p+p -----> p+p+ Pi^{0}

If all particles produced at rest what must be the KE of the initial protons

2. Relevant equations

mass of Pi^{0}= 135MeV/c^{2}

3. The attempt at a solution

Total energy of the system, E= mc^{2}

Mass of proton = 1.6726 *10^{-27}Kg

Hence initial energy = 2* 1.6726*10^{-27}*2.99*10^{8}*2.99*10^{8}

But in this case why do I need the mass of Pi 0...I guess I am terribly worng pls help
