The mass of a proton is 1836 times the mass of an electron. (a) A proton is traveling at speed V. At what speed (in terms of V) would an electron have the same kinetic energy as the proton? (b) An electron has kinetic energy K. If a proton has the same speed as the electron, what is its kinetic energy (in terms of K)?
