If both cars are the same mass and hit each other at the same speed (in opposite directions): 1.) They both come to a stop.

2.) They come out of the collision at random speeds.

3.) They come out of the collision at the same speeds they entered it.

4.) They come out of the collision at the same velocities they entered it.

It is the angle the incident ray makes with a line drawn perpendicular to the reflecting surface. ✓

Explanation:

The law of reflection states that the angle of reflection equals the angle of incidence-er Oi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface.
