Use the following information to answer this anaholistic question. James Chadwick is credited with the discovery of the neutron. He used a radioactive source that contained polonium-210 to produce a stream of high-energy alpha particles (v=1.59 x 10" m/s). In the experiment, the alpha particles were directed at a beryllium target. Occasionally, an alpha particle would hit a beryllium nucleus and knock a high-energy particle free. The system created by the radioactive decay of a nucleus of polonium-210 includes the alpha particle and the daughter nucleus (m = 3.42 x Tige kg) and can be modelled as an 1solated system. This permits an analysis in which the increase in kinetic energy of the system results from a loss in measurable mass in the system
