Ernest Rutherford (the first New Zealander to be awarded the Nobel Prize in Chemistry) demonstrated that nuclei were very small and dense by scattering helium-4 nuclei from gold-197 nuclei. The energy of the incoming helium nucleus was 8.00\times 10^{-13}~\text{J}8.00Γ10 β13 J, and the masses of the helium and gold nuclei were 6.68\times 10^{-27}~\text{kg}6.68Γ10 β27 kg and 3.29\times 10^{-25}~\text{kg}3.29Γ10 β25 kg, respectively (note that their mass ratio is 4 to 197). If a helium nucleus scatters to an angle of 120^\circ120 β during an elastic collision with a gold nucleus, what is the final kinetic energy of the helium nucleus?
