Question
A particle has rest mass 6.64 $\times$ 10$^{-27}$ kg and momentum 2.10 $\times$ 10$^{-18}$ kg $\bullet$ m/s. (a) What is the total energy (kinetic plus rest energy) of the particle? (b) What is the kinetic energy of the particle? (c) What is the ratio of the kinetic energy to the rest energy of the particle?
Step 1
Step 1: The total energy of a particle is given by the equation $E = \sqrt{(mc^2)^2 + (pc)^2}$, where $m$ is the rest mass of the particle, $c$ is the speed of light, and $p$ is the momentum of the particle. Show more…
