Then, all three of them massively, quickly, violently, straighten the dog doo-doo out of their right arms toward impact.
The real question is :
a) Does the golfer consciously trying to straighten his right arm or
b) Does the force of the clubhead motion overcome the force the golfer is using to keep his arm bend, generating quick violently straightening of the right arm or
c) Does the force of the clubhead motion reaches a certain peak value generating a trigger point for the golfer to unconsciously releasing the muscle that kept the right arm bend, so that the force of the clubhead motion is used to straighten the arm
---> and thus creating in those 3 scenarios the exact same diagram!
