A) An unstable particle at rest breaks up into two fragments of unequal mass. The mass of the lighter fragment is equal to 2.00 10-28 kg and that of the heavier fragment is 1.60 10-27 kg. If the lighter fragment has a speed of 0.893c after the breakup, what is the speed of the heavier fragment?

B) An unstable particle with a mass equal to 3.34 ? 10-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.988c and -0.865c, respectively. Find the masses of the fragments. (Hint: Conserve both mass-energy and momentum.)

m(0.988c) =

m(-0.865c) =
