A uranium-238 atom can break up into a thorium-234 atom and a particle called an alpha particle, α-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10−27 kg). When an uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.9 × 105 m/s. How much of the uranium atom's internal energy is released in the breakup?

    So how would I figure this out?

    I understand what the inertias are because you just multiply 238, 234, and 4 by 1.66x10-27

    what are the moments of inertia?
