A 23'Tb (thorium) nucleus at rest decays to a 228Ra (radium) nucleus with the emission of an alpha particle. The total kinetic energy of the decay fragments is 6.54 X 10-13 J. An alpha particle has 1.16% of the mass of a 228Ra nucleus. Calculate the kinetic energy of
(a) The recoiling 228Ra nucleus and
(b) The alpha particle
