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 (4He) from gold-197 nuclei (197Au). The energy of the incoming helium nucleus was 8.30x10-13), and the masses of the helium and gold nuclei were 6.68x10-27 kg and 3.29x10-25 kg, respectively (note that their mass ratio is 4 to 197). If a helium nucleus scatters to an angle of 118° during an elastic collision with a gold nucleus, calculate the helium nucleus's final speed. 1.56x107 m/s You are correct.

Question

First part is already answered but the process would still be appreciated. 

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 (4He) from gold-197 nuclei (197Au). The energy of the incoming helium nucleus was 8.30×10-13 J, and the masses of the helium and gold nuclei were 6.68x10-27 kg and 3.29×10-25 kg, respectively (note that their mass ratio is 4 to 197). If a helium nucleus scatters to an angle of 118° during an elastic collision with a gold nucleus, calculate the helium nucleus's final speed. 1.56x107 m/s You are correct. Your receipt no. is 162-7739? Calculate the magnitude of final velocity of the gold nucleus. Submit Answer Incorrect. Tries 15/99 Previous Tries Calculate the direction of final velocity of the gold nucleus. Measure the angle from the initial direction of the helium nucleus. Submit Answer Tries 0/99 What is the final Previous Tries kinetic energy of the helium nucleus? Submit Answer Tries 0/99
