A5-kg fish swallows an absent minded 1-kg fish swimming toward 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? you and your friend toss a ball back and forth in the middle aisle of an airplane in flight. does the kinetic energy of the ball depend on the speed of the airplane?
