Verify that a boost in the x-direction that any object traveling at speed c in an inertial frame S travels at speed c in the boosted frame.

Verify directly from the form of the Lorentz transformation representing a boost in the x-direction that any object traveling at speed c in an inertial frame S travels at speed…
