Simple Momentum Question

[Jatsix30]

A compact car and a large truck collide head on and stick together. Which undergoes the larger momentum change? 1) Truck, 2) Car, 3) The momentum change is the same for both vehicles, or 4) Cannot tell without knowing the final velocity of the combined mass.

:uhh: i thought it was car, since the large mass of the truck increases the combined mass more so for the car, thus p=mv would be increased more also... bleh, i'm kinda new at momentum

Question for you: Is momentum conserved in the collision?

[Jatsix30]

I think momentum is conserved... so would the momentum change be the same for the car and truck?

Hint:
Is the following statement true or false:

The momentum change of the system equals the sum of the momentum changes for car and truck.
