Changing Momentum

The illustrations show two ways of providing impulse to change the momentum of a vehicle. In the top illustration, the vehicle collides with a massive concrete barrier. In the bottom illustration, the vehicle collides with water-filled barrels.

*two illustrations are shown one above the other. The top illustration shows a car with a crash test dummy behind the wheel being driven into a cement barrier. The bottom illustration shows a car with a crash test dummy behind the wheel being driven into barrels containing water.*

Explain which type of crash barrier would likely produce less damage to the vehicle and less injury to the occupants.
