Question
A proton (rest mass 1.67 $\times$ 10$^{-27}$ kg) has total energy that is 4.00 times its rest energy. What are (a) the kinetic energy of the proton; (b) the magnitude of the momentum of the proton; (c) the speed of the proton?
Step 1
The rest energy of a particle is given by the equation $E = mc^2$, where $m$ is the rest mass of the particle and $c$ is the speed of light. Therefore, the total energy of the proton is $E = 4mc^2$. Show more…
