In a laboratory experiment, two protons are accelerated towards each other at very high speeds to make them collide together. To the people in the laboratory, they see proton 1 traveling at a velocity of = 0.7000c, and proton 2 traveling at a velocity of 7 = 0.6345c. -27 1.67 x 107 kg = 9.38 10 eV/c. Thus, their mass-energy is mc = 9.38 10 eV. Protons have a mass of = mp (The following question(s) must be answered to within 1% of the expected value to be graded as correct.) What is the velocity of proton 1 from the perspective of proton 2? Answer as a fraction of the speed of light, c. C From the perspective of the laboratory technicians, what is the total energy of both protons combined? That is, what is E + E? x108 eV
