At your next meeting of "Meddling Mental Midgets", at 4,000 frames per second develop a concensus concerning your findings.
Using Inertia as the cause of the bat head trailing the lighter faster base being propelled in a circular motion, please have your group determine the benefits of making contact with the target at a less than 90 degree angle in the arc of travel of the bat head to the target (ball).
Further, explain the elastic tendencies of the materials used in the bat.
Further still, you may want to point out that bats of certain materials lack elastic strength and thus will shatter due to the forces placed on the elastic deficient areas of the bat.
In your acceleration example, you make plain that objects not accelerating will be dragged behind the accelerating body or will be left behind. The method you are proposing has the bat making contact while the bat is still facing backwards because it has yet to catch up with the original accelerating body, the base of the bat.
In the strong front side or stong front foot, your method would have a better chance at reaching a 90 degree contact point generating a larger amount of force into contact. But this is not what you are promoting.
Have a meeting, make a film of the swing you endorse and then sit and laugh at yourselves for trying to make contact with a bat that is bent backwards.
LAball,
if your wrists are rolling, your swing is bad. Your wrists have the capability to move an object held in the hands in over a 180 degree arc with no roll.
