Unformatted text preview: A moves with a speed u and B moves with a speed v . They both move in straight lines, with an angle θ between their trajectories (again in the lab frame). What is the speed of A as seen from the reference frame of B ? 6. K&K, Problem 13.1 7. At the Cornell accelerator CESR, each electron has an energy of E = 5 GeV (or 10 9 eV). At the Large Hadron Collider (LHC) at CERN, each proton will have an energy of E = 7 TeV (10 12 eV). The rest mass of the electron is 9.11 × 10-31 kg, while the rest mass of the proton is 1 . 67 × 10 27 kg. What is γ for an electron at CESR or a proton at LHC? What is the diﬀerence in speed from the speed of light, c-v , for a CESR electron or an LHC proton? Why might someone think this answer might appear strange?...
