Question
Show analytically that a particle with momentum $p$ and energy $E$ has a speed given by$$v=\frac{p c^{2}}{E}=\frac{p c}{\sqrt{m^{2} c^{2}+p^{2}}}$$
Step 1
Here, $\gamma$ is the Lorentz factor, $m$ is the mass of the particle, $v$ is the velocity of the particle, and $p$ is the momentum of the particle. Show more…
