A 232 Th (thorium) nucleus at rest decays to a 228 Ra (radon) nucleus with the emission of an alpha particle. The total kinetic energy of the decay fragments is 6.54 x 10^-3 J. An alpha particle has 1.76% of the mass of a 228 Ra nucleus.
a) Calculate the kinetic energy of the recoiling 228 Ra nucleus.
b) Calculate the kinetic energy of the alpha particle.
