An explosion breaks a rock into three parts in a horizontal plane. Two of them go off at right angles to each other. The first part of mass 1 kg moves with a speed of $12 m s ^{-1}$ and the second part of mass 2 kg moves with $8 m s ^{-1}$ speed. If the third part flies off with $4 m s ^{-1}$ speed, then its mass is
