Not a scientific answer, but an observation

Not at all uncommon in golf with a wedge shot hit comparatively softly and with a ball trajectory up and through the area of the club follow through. This is not at all similar, in my opinion, to the relatively high speed collisions of other irons and woods with trajectories outside the club's follow through arc. Also, in my opinion, this is not at all analogous to the baseball, tennis, racquetball, and/or table tennis examples wherein the ball is hit with speed and, again, with a trajectory outside the resultant path of the striking object. I think the important factors include relative sizes of the two colliding objects; compressibility/deformability of the colliding objects (lending to duration of impact); the spin of a moving ball (tennis balls are particularly conducive to high rates of spin); the relative angles of approach in the collision; and the speed and angle of trajectory of the resultant path of the stricken ball.

I'll be very interested in seeing the comments of some of Chuck's profs friends upon their more detailed analyses.
