Two protons (each with rest mass M=1.67×10?27kg) are initially moving with equal speeds in opposite directions. The protons continue to exist after a collision that also produces an ?0 particle. The rest mass of the ?0is m=9.75×10?28kg.
A. If the two protons and the ?0 are all at rest after the collision, find the initial speed of the protons, expressed as a fraction of the speed of light.
B. What is the kinetic energy of each proton? Express your answer in MeV.
C. What is the rest energy of the ?0, expressed in MeV?
