have the same velocity after the collision, the kinetic energy required for this process is a minimum. Use a relativistic calculation to show that KE min = 6mc 2 , where m is the rest mass of the electron. Energy and Momentum 16. What is the energy of a photon whose momentum is the same as that of a proton whose kinetic energy is 10.0 MeV? 17. Find the momentum (in MeV/c) of an electron whose speed is 0.600c. 18. Find the total energy and kinetic energy (in GeV) and the momentum (in GeV/c) of a proton whose speed is 0.900c. The mass of the proton is 0.938 GeV/c 2 . 19. Verify that ࠵? / ࠵? = ࠵?࠵? / ࠵? . 20. Find the speed and momentum (in GeV/c) of a proton whose total energy is 3.500 GeV.
3/3 21. Find the total energy of a neutron (m = 0.940 GeV/c 2 ) whose momentum is 1.200 GeV/c. 22. A particle has a kinetic energy of 62 MeV and a momentum of 335 MeV/c. Find its mass (in MeV/c 2 ) and speed (as a fraction of c). 23. a. Find the mass (in GeV/c 2 ) of a particle whose total energy is 4.00 GeV and whose momentum is 1.45 GeV/c. b. Find the total energy of this particle in a reference frame in which its momentum is 2.00 GeV/c.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
