Davis is comparing the strength of elastic energy of three rubber bands of different sizes. Of the following choices, which one would be the BEST way for him to prove the relative elastic energy of each rubber band?

Shoot the same acorn from each rubber band while pulling the rubber band as far back as possible for each shot. The rubber band that launches the acorn the farthest is the strongest.
