Given information
A proton and antiproton are travelling towards each other at the same speed.
Step-by-step explanation
Step 1.
The two particles have the same mass and they are traveling at the same speed towards each other, hence the total momentum of the system is zero.
The minimum kinetic energy of the collision must be equal to the mass-energy of pair.
