Creating a Particle. Two protons (each with rest mass M = 1.67 × 10 −27 kg) are initially moving with equal speeds in opposite directions. The protons continue to exist after a collision that also produces an η 0 particle (see Chapter 44). The rest mass of the η 0 is m = 9.75 × 10 −28 kg. (a) If the two protons and the 17° 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 η 0 , expressed in MeV? (d) Discuss the relationship between the answers to parts (b) and (c).

Definition Definition Rate at which light travels, measured in a vacuum. The speed of light is a universal physical constant used in many areas of physics, most commonly denoted by the letter c . The value of the speed of light c = 299,792,458 m/s, but for most of the calculations, the value of the speed of light is approximated as c = 3 x 10 8 m/s.
