Problem: True/False(a) As a tile falls from the roof of a building to the ground, its momentum is conserved.(b) When a baseball player hits a home run, the baseball receives a greater impulse from the bat than the bat does from the ball.(c) In a ballistics test, a bullet traveling horizontally strikes and embeds itself in a large block that is free to move. During this process, the bullet transfers all of its momentum to the block.

Impulse:

I=Ft

(a)

The earth is used as a stationary reference point. The gravitational force acting on the tile is considered as an external force that increases the velocity and momentum of the tile. The momentum will only be conserved if we include the earth to be part of the system.
