What is the velocity of the more massive fragment

Reference no: EM13549873

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 +0.720c and a mass of 1.27 10-27 kg, while the other has a mass of 4.11 10-27 kg. What is the velocity of the more massive fragment?
