Two protons (each with rest mass M = 1.67 x 10-27 kg) are initially moving with equal speeds in opposite directions. The protons continue to exist after a collision that also produces an h0 particle. The rest mass of the h0 is m = 9.75 x 10-28 kg. (a) If the two protons and the h0 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 h0 , expressed in MeV? (d) Discuss the relationship between the answers to parts (b) and (c)
