well the massive truck will have more of a change in velocity than the small car since more mass means more change in velocity.

Right???

right
so the car and truck do not change velocities at the same rate, which makes the origional statement false.

no the less massive object will have a more change of a velocity due to the more massive object. But the origonal statement is still false, right??
