2. Calculate the momentum, kinetic energy, and total energy of an electron traveling at a speed of 0.744c.

Einstein's famous equation E=mc2 means _______. a small amount of energy is equivalent to a very large amount of matter matter will change into energy if it moves with a velocity of c     matter and energy are the same thinga small amount of matter is equivalent to a very large amount of energy

plz do both

5: Write down Lorentz transformation equations of special theory of relativity. Can a person, in principle, travel from Earth to the galactic center (which is about 23000ly distant) in 100 years?
