What will be the speed of this recoiling nucleus

Reference no: EM13538302

An atomic nucleus at rest decays radioactively into an alpha particle and a smaller nucleus. What will be the speed of this recoiling nucleus if the speed of the alpha particle is 2.3×105 m/s ? Assume the recoiling nucleus has a mass 57 times greater than that of the alpha particle.
