holy crap, do you think a clock is that difficult? you could have also used an easier description, while I understand what you're saying it's just you're making a simple concept way too hard.
Consider the ball in the air to be an open face clock.
If it is directly above your head, you are directly under 6:00.
If you hit it from the side across, you go from 3 to 9.
If you hit it from the bottom to the top(ie kick) you go roughly 6 to 12.
