[Golfie McG]

GMcG,
doesn't the above calculation make the assumption that all the difference in KE from 100 to 150 mph is transferred to the ball?...i don't think a 150 mph impact speed clubhead slows to 100 mph during impact...anyway, as i've said before i think it is the equation F=ma that answers the distance question and not velocity but acceleration at impact that makes the most difference (assuming equal clubs and equally good ball contact) and that is why slow easy swings with late release and therefore high late acceleration can hit the ball as far or farther than some really hard swings.

Hcw,

Calculation used to determine the relative amounts of energy required by the Golfing Machine to reach various velocities – not modeling around impact.

Other matters you allude to such as seemingly slow swingers out hitting those moving faster are cases of efficient transfer of power producing late clubhead speed. This is a matter of technique.
