Thomas Jefferson National Accelerator Facility in Newport News, Virginia, is host to a continuous electron beam. Within the facility, electrons travel around a 7/8 -mi-long tunnel five times in 23.5 millionths of a second. (Actually, the facility is capable of producing even higher speeds.) (a) What is the speed of the electrons? (b) Determine the length around the tunnel as measured in the reference frame of the electrons. (c) Determine the time it takes for the electrons to complete one lap around the tunnel in the reference frame of the electrons. (d) What are the momentum and kinetic energy of the electrons?
