What is the speed of the heavier fragment

Reference no: EM13668343

An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is 2.70*10^-28 kg and that of the heavier fragment is 1.65*10^-27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment?
