A proton moves with a speed of 0.955c.
(a) Calculate its rest energy.
MeV
(b) Calculate its total energy.
GeV
(c) Calculate its kinetic energy.
Velma passes Mort at a speed of 0.75c. At this speed, the "time dilation factor" is 1.5. In other words, Mort observes a 1-second tick of Velma's clock to take 1.5seconds. assume that they are born at the same time, and that Mort observes himself ..
