If we have to figure air resistance into it, then we don't have enough information to find an answer.
If the air around it is going to have an effect on how it falls, then it'll depend on the thickness of the book, the shape of the book, whether it's a hard-cover or soft-cover, how far the covers stick out past the pages, how smooth or rough the covers are, how bumpy the binding it. and what position you hold it in before you let it go.
(THAT's why we always ignore air resistance, especially when the question is actually about gravity anyway.)
I can't read any of it... Please type a reply comment to this comment, with the questions, and I will help you.
It is real, however it gets inverted in the retina and flips back in the cornea
True. Force is acceleration therefor inverse force is increasing acceleration
