The rest energy E of an object is given by Albert Einstein's famous equation E=mc2, where c is the speed of light in a vacuum. Calculate E to three significant figures for an electron with mass m=9.11x10-31 kg. The SI unit for E is the Joule (J); 1 J= 1 kg*m/s2. The speed of light is 2.99792458x108 m/s
