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 -2.6 × 10^5 m/s. How much of the uranium atom's internal energy is released in the breakup?
Homework Answers
Concept: we use momentum conservation to find
out the speed of alpha particle after breakup and then we find
kinetic energy of both particles to find out the energy released,

The numbers indicate the inertias of the atoms and the alpha particle in atomic mass units (1 amu = 1.66 × 10−27 kg). When a uranium atom initially at rest breaks up, the thorium atom is observed to recoil with an x component of velocity of -2.2 × 105 m/s. Please give the answer in Joules

A uranium nucleus (mass 238 u), initially at rest, undergoes a radioactive decay. After an alpha particle ( mass 4.0 u) is emitted, the remaining nucleus is thorium (mass 234 u). If the alpha particle is moving at 0.050 times the speed of light, what is the recoil speed of the thorium nucleus?
