Suppose that an atomic nucleus of mass m2 collides with a second nuclear particle of mass m1. If the

Suppose that an minute central-part of majority m2 collides after a while a avoid nuclear atom of majority m1. If the minute central-part is initially at repose, and the swiftness of the avoid nuclear atom is moderate by 50%, what is the majority of the minute central-part? Assume that the majority of the avoid nuclear atom is 1 AMU.
