what does that have to do with measuring distance
Theres 1200 Ib of force he creates in a 10th of a second, I think his proprioceptive ability is brilliant,it was in relation to where force comes from, I believe from another poster, who has that many names i thought you were him, sorry .
First off the head pops up, so it does move... What you have done is to write it out in prose telling us to push off the back... Big mistake since the head does move which is why Dempsey said to step in from the front foot to keep the head down. study the mechanics/physics of the trebuchet were power and more can be accomplished off the front foot. Plus we could say the front foot is your distance it doesn't mean anything.
Were talking proprioceptive ability, if you see the relevance.
