Never said that the driving force was mass, but that mass affects the kinetic energy and is a variable.
And as im thinking about it, it is possible that i may have used the wrong comparison, but the ft lds of force impacted on the body in all of the charts i have seen with ft lbs, is way higher in the 45 than the 40 and ft lbs translates to kinetic energy right?
If not let me know....got me scratching my head on where my equation would be flawed and how ft lbs affects witch variable in the equation...Thanks for my daily puzzle...
