A 5-kg fish swallows an absentminded 1-kg fish swimming towards it at a velocity that brings both fish to a halt immediately after lunch. What is the velocity of the smaller fish before it becomes lunch? Use the concepts of this chapter to describe what would happen if you fire a gun that has bullet ten times as massive as the gun. An apple falls from a tree and strikes the ground without bouncing. What happens to its momentum? Is momentum conserved?
