Re: Depends on how slow the hare is.
 

It's clear from watching guys like Woods and Kuehne that their velo is NOT just due to a delayed release of #2. In Woods case, his shoulder thrust gets a turbo boost from unbelievable hip rotation. Since going to a big headed driver with 45" shaft, he is leading the tour in distance with a swing he describes as "wide and tight".

I use Hitting only with the shorter irons and putter.

lagster,

"WHERE IN THE SWING DO THE LONGEST HITTERS HAVE THE GREATEST ACCELERATION? How do they accomplish this?"

Do you mean the greatest clubhead speed? That's an interesting question. I have read that the max velo happens before Impact even in the best swings. With all the tech available today, it seems like we should know for sure. Woods does it with hip rotation and shoulder thrust.

What is your reference to mass about? I think that if you could model Woods with a stick man made of titanium, weighing say 30 lbs, and it's hips and right shoulder, etc. moved just like Woods, the ball would go the same distance.

MizunoJoe,

Acceleration is a little different than velocity or speed. 8-9 SECTON 9, for example, is listed as the period of Clubhead Acceleration.

Now... HIP SPEED is another topic. That is interesting. I have heard that the fastest that the hips can turn is something like 7 MPH or so. So... how much does this actually contribute to one's CLUBHEAD SPEED?

At Release, the Clubhead acceleration period begins which gives the Clubhead it's speed.

Have you ever seen Wood's hip speed up close? It kick starts the Right Shoulder thrust. He does it just like Hogan says in Five Lessons.

[quote="lagster"]Considering the maximum hip speed, around 2mph from what I have read, and their limited range of motion, hip speed is not of no real consequence in the production of clubhead speed.

Fast moving hips (Tiger e.g) are only anecessity in order to clear a route for faster moving arms, which are the true speed generators; the right arm in particular.

The most powerful swings are ground-up motions in which the hip rotation initiates and aids the shoulder uncoiling. You can uncoil over a passive lower body, but it's not as powerful - the Faldo makeover by Leadbetter is a good example.

And, how does the Right Arm contribute to Left Arm speed in a Swinging Procedure using Accumulators 4, 2, and 3?

releasing clubhead as late as possible while still getting back to the ball (ie mj's snap release)

There is no such thing as "a ground up motion" - all golf swings are top to bottom motions with only reaction - or resistance - to the force generated being provided, and felt, from the ground up. Newtons third law - (paraphrased) all actions have an equal and opposite reaction.

I will answer your other question with a question of my own - do you know of anyone who hits a golf ball as far with his left hand only as he does with both hands on the club, be he a swinger or a hitter?

If you understand the action of throwing a ball, you'll understand what Burner is talking about....

It's interesting that 10-3-B reads, "a Right Forearm Underhand Pitch is delivered at the Aiming Point with a stiff-wrist slapping motion".
