Which of the following diagrams best represents the forces on the automobile

Beautiful !

You haven't given us the diagrams to choose from, but that's OK
because you haven't told us anything about the forces either.

A classic twofer !

This is what i found on google “according to the collision theory, the following criteria must be met in order for a chemical reaction to occur: molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. molecules must collide with the proper orientation.” i hope this information you.
