Still think 135 mph baseball will not RISE? Well using your info, I calculated a 1 pound bowling ball will have to travel faster then 432 mph to get any LIFT at all.

I know one thing, from 60 feet it may not rise. Are you happy? Don't be, because at that velocity I doubt gravity will have much of an influence either. I can almost guarantee a horizontal flight path over 60 feet. My question is how long will it stay airbourne and what speed will it be traveling when it hits the ground? Then you have a measure of deceleration and drag.

Now take the LIFT coefficient of a NON-spinning leather cowhide baseball WITH SEAMS traveling 100 mph and compare it to a smooth concrete bowling ball withOUT SEAMS traveling 432 mph across 60 feet. Care to bet which has a greater chance of RISING?

But I suppose your physics friends wouldn't wanna answer that. Because if they did, you would have to SAY YOUR WRONG, baseballs can rise if thrown hard enough. Again, it has nothing to do with SPIN, its LIFT! Something NEWTON didn't work on back in the 1600's. Care to ask your physics friends how many feet of concrete or STEEL can stop a 432 mph bowling ball after 60 feet. I think the Momentum Effect would project right through 10 feet of concrete or 3 feet of steel. But I just made that up because it sounds good. Doesn't matter anyway because back in the 1600's ships were made out of wood and airplanes didn't exist. Yep, time to update your physics books again!

God, you're funny.
