The relativistic kinetic energy is given by K = mc^2 / sqrt(1 - (v^2 / c^2)) - mc^2 = (γ - 1)mc^2. Show that for v much smaller than c the relativistic equation reduces to classic equation. Plot the graph K x v, for v = 0; v = 0.1c; v = 0.2c; ...; v = c and interpret.

The relativistic kinetic energy of a particle is three times its rest mass energy. Find the: a) Lorentz factor and speed parameter b) velocity (in m/s) of the particle.

Make a graph of the relativistic factor γ = 1/(1 − v²/c²)¹/² as a function of β = v/c. Use at least 10 values of β ranging from 0 up to 0.995.
