According to the theory of relativity by Einstein, the mass of a particle is given by the formula:

a.) Make 'v' the subject of the formula
b.) Find the velocity necessary to increase the mass of a particle to three times its rest mass, i.e., m=3m. Give the value for 'v' as a fraction of 'c'.
c.) A cyclotron increased the mass of an electron to 30m. With what velocity must the electron have been traveling? [note: c=3x10^8 m/s]
