c = 3e+008; // Speed of light in vacuum, m/s
E0 = 1; // Rest energy of particle, unit
E = 3*E0; // Energy of relativistically moving particle, unit
// E = m*c^2 and E0 = m0*c^2
// With m = m0/sqrt(1-v^2/c^2), we have
v = c*sqrt(1-(E0/E)^2); // Velocity of the moving particle, m/s

// Result
// The velocity of the moving particle = 2.83e+008 m/s
