Problem P. 3816. (September 2005)

P. 3816. Two bodies collide. Before the collision the linear momentum of one of them was 3~\rm
kg\,m/s, and the other was at rest. After the collision can the linear momentum of the second body (which was initially at rest) be 4~\rm kg\,m/s? If yes, at which case?
