Question: A uranium-238 atom can break up into a thorium-234 atom and a particle called an alpha particle, a±-4. The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 x 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 -280000 m/s.
Part A: How much of the uranium atom's internal energy is released in the breakup?
