Answer:
Muscle contraction is the activation of tension-generating sites within muscle fibers. In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as by holding a heavy book or a dumbbell at the same position. The termination of muscle contraction is followed by muscle relaxation, which is a return of the muscle fibers to their low tension-generating state.

Answer:
Using logical reasoning, if they collided front to front the engines would have a chance of implosion. But unless they aren't the same type of vehicle, e.g. a honda civic hitting a honda civic, there wouldn't be as much damage as the same vehicles hitting each other. Unless the counterpart is taking in big trucks aswell, such as a semi hitting a bus, then there would be a mainstreet explosionary blast most likely. But either way both will be messed up BAD.
