A particle has y=15,687. Calculate c-v in m/s. (I would have asked for 1- v/c, making the answer dimensionless, but the system doesn't seem to take numbers that small. Gamma is chosen to make the particle extremely close to the speed of light.) If your calculator gives problems, you might want to solve the appropriate equation for c-v or c(1- v/c) and use an approximation.

Question

In the previous problem, in a race to the moon, by 3/4ths the distance, light is one or ten meters ahead of the particle.  We routinely approximate mass as zero, gamma as infinite, and speed as the speed of light.  ("Massless particles" -- gamma and m have to be eliminated from the expressions.  Light is a true massless particle.)

If a massless particle has momentum 536 MeV/c, calculate its energy in MeV.

 

I attached the previous problem as well for reference.
