An unstable particle with a mass equal to 3.34 multiplied by 10-27 kg is initially at rest. The particle decays into two fragments that fly off with velocities of 0.981c and -0.864c, respectively. Find the masses of the fragments. (Hint: Conserve both mass-energy and momentum.)
m(0.981c) =_____kgm(-0.864c) =____kg
