The mass of a proton at rest is m.If the proton is moving so fast that its total energy is four times its rest energy,then what is the kinetic energy of the proton? A) 3mc² B) mc² C) 2mc² D) 4mc²

Question

Quizplus · Accepted Answer

The total energy of the proton is given as four times its rest energy, which is 4mc². The rest energy is mc². The kinetic energy is the total energy minus the rest energy, which is 4mc² - mc² = 3mc².
