The rest energy of an electron is 0.511 MeV. The rest energy of a proton is 938 MeV. Assume both particles have kinetic energies of 1.70 MeV.
(a) Find the speed of the electron.
c
(b) Find the speed of the proton.
(c) By how much does the speed of the electron exceed that of the proton?
(d) Repeat the calculations assuming both particles have kinetic energies of 1800 MeV. electron's speed m/s proton's speed m/s exceeded speed m/s
