Review Conceptual Example 5 as background for this problem. The a decay of uranium ²³⁸₉₂U produces thorium ²³⁴₉₀^TH  (atomic mass = 234.0436 u). In Example 4, the energy released in this decay is determined to be 4.3 MeV. Determine how much of this energy is carried away by the recoiling ²³⁴₉₀^TH  daughter nucleus and how much by the a particle (atomic mass = 4.002 603 u). Assume that the energy of each particle is kinetic energy, and ignore the small amount of energy carried away by the g ray that is also emitted. In addition, ignore relativistic effects.
