What angle maximizes air time for a launched ball?

[pyroknife]

I was just wondering, let's say you launch a ball, what angle would give you the longest time in the air? I know that 45 degrees will make it go the farthest but is that also for longest time in the air?

Simply 90°. Why? Because the ball will go higher than a pitched ball with the same impulse. It will take longer getting at its higher peak than a ball pitched with the same impulse but with a different angle. Furthermore it has to go down... which also will take longer.

Oh I see thanks

Yeah, but even more so, it will be because the "y component" of the velocity will be greatest at 90 degrees.
