In this question, "A stationary body explodes into two fragments each of mass 1.0 kg that move apart at speeds of 0.6c relative to the original body. Find the mass of the original body."
My first thought is that you need to use the law of conservation of momentum.
However, how do you take relativity into account since the pieces move near the speed of light?
