Two cars (A and B) of mass 1.1 kg collide. Car A is initially moving at 18 m/s, and car B is initially moving in the opposite direction with a speed of 9 m/s. The two cars are moving along a straight line before and after the collision. (Enter the magnitudes.)
If the two cars have a completely inelastic collision, calculate the change in momentum (in kg · m/s) of the two-car system.

This is nuts. There is no change of momentum, momentum is conserved, PERIOD.
