• 11.
If a small rock and a large rock are both thrown at a wall at exactly the same speed, which rock would most likely cause more damage to the wall?
• A.

The large rock would cause more damage because the force would be spread out on a larger area.

• B.

The large rock would cause more damage because it has a greater mass, making the momentum greater.

• C.

The small rock would cause more damage because it has a smaller mass, making the momentum greater.

• D.

The small rock would cause more damage because all of the force would be concentrated on one small area.
