Use the equation m = mo/sqrt1-v^2/c^2 to show that travelling at the speed of light or beyond is impossible.

An electron has a rest mass of 9.11 x 10^-31 kg. The speed of the time electron in the cathode ray tube of your computer monitor is 4.00 x 10^7 m/s. However, the speed of the electron i s0.98 c in a particle accelerator used in cancer therapy. How many times heavier is the electron in the particle accelerator than in the computer monitor?
