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 produces an η0 particle. The rest mass of the η0 is mη=9.75×10−28kg.
Part A
If the two protons and the η0 are all at rest after the collision, find the initial speed v of the protons.
Express your answer as a fraction of the speed of light to three significant figures.
v =c
Part B
What is the kinetic energy Ek of each proton?
Express your answer in millions of electron volts to three significant figures.
Ek =MeV
Part C
What is the rest energy Er of the η0?
Express your answer in millions of electron volts to three significant figures.
Er =MeV
