Dude…seriously? are you serious?
Basic physics can not be applied to the jumps or throws…any half decent coach knows this…
The fact that you are going from a physics text book and not a BIOMACHANICS text book is the reason why your do not know what your talking about. I am sorry that you don’t understand. Really i am.
We are dealing with the HUMAN BODY here…not a Missile being launched from the ground.
So are you saying that all research, biomachanics analysis of jumps, coaching litt, kinematic long jump models etc etc are wrong? ? ?
I am shaking my head in disbelief. You are out of your mind and I am out of here…
