The spontaneous decay of a heavy atomic nucleus of mass M = 16.5 ? 10?27 kg that is initially at rest produces three particles. The first particle, with mass m1 = 6.64 ? 10?27 kg, is ejected in the positive x direction with a speed of 1.70 ? 107 m/s. The second particle, with mass m2 = 3.40 ? 10?27 kg, is ejected in the negative y direction with a speed of 2.00 ? 107 m/s. (a) What is the...

A nucleus whose mass is 3.730032 x 10-25 kg undergoes spontaneous "alpha" decay. The original nucleus disappears and there appear two new particles: a He-4 nucleus of mass 6.640678x10-27 kg (an "alpha particle" consisting of two protons and two neutrons) and a new nucleus of mass 3.663533 x 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). In these calculations, it is very important to...
