An unstable particle is at rest and suddenly breaks up into two fragments. No external forces act on the particle or its fragments. One of the fragments has a velocity of +0.800c and a mass of 1.87 10-27 kg, while the other has a mass of 4.31 10-27 kg. What is the velocity of the more massive fragment?
