proton rest mass, mo = 1.67*10-27 kg
rest mass energy = mo c^2 =1.67*10-27 *9*10^16
rest mass energy = 1.5*10-10 Joule = 937.5*10^6 eV = 937.5MeV
----------------------------------------
Total energy = E = m c^2
E = moc^2/√[1-(v/c)^2] = 1.5*10^-10 /√[1-(v/c)^2]
E = 1.5*10^-10 /√[1-(0.9)^2] = 1.5*10^-10 /√[0.19]
E = 3.44*10^-10 J
---------------------------
kinetic energy
KE = m c^2 - moc^2 = Total energy - rest energy
KE = (3.44 - 1.5)*10^-10 Joule
KE = 1.94*10^-10 J

1)The equation E = mc ^ 2 we have: E=0.6*(3*10^8)^3=16.2*10^24 For two-dimensional kinetic energy with the energy obtained is equal and is equal to the total energy.
