E^2 = p^2c^2 + m0^2c^4

Where E = energy

Where p = momentum

Where c = the speed of light

Where m0 = rest 'mass' in energy

Can anyone please work out this forumula for me to make p the subject and then find a way to dispose of v so that all we have left is the energy?

In other words, p = ev (or p = mv) the m here being the mass in energy. Once ev is the subject (as p) can you find a way to get rid of v in favour of just having v please? My rearranging maths is terrible. Please can someone help me.

Thanks,
