A nucleus whose mass is 3.772516 x 10-25 kg undergoes spontaneous alpha decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678 x 10 27 kg (an alpha particle consisting of two protons and two neutrons) and a new nucleus of mass 3.706016 10 25 kg. (Note that the new nucleus has less mass than the original nucleus, and it has two fewer protons and two fewer neutrons). Part 1 (a) When the alpha particle has moved far away from the new nucleus (so the electric interactions are negligible), what is the combined kinetic energy of the alpha particle and new nucleus? Save for Later Using multiple attempts will impact your score. 20% score reduction after attempt 2 Part 2 Attempts: 0 of 4 used Submit Answer (b) Use the Conservation of Momentum in order to determine the kinetic energy of the alpha particle and the kinetic energy of the new nucleus.
