A nucleus moving with velocity v emits an alpha particle. Let the velocities of the alpha particle and the remaining nucleus be v1 and v2 and their masses be m1 and m2, then A nucleus moving with velocity v emits an alpha particle. Let the velocities of the alpha particle and the remaining nucleus be [...]
