It's pretty interesting.

As-is I suspect our shooter gets the ball far enough to cover half the field before it hits the ground again, which is good enough for a ball-delivery bot should the situation arise. Once we get a starting point for a more realistic motor/gearbox we'll adjust speed with some extra room for maximum "oomph" (and also some breathing room for drained batteries). It won't do full-field shots, but we're not trying to do those in the first place. At best we'll try to hit the mid or high goal from ~24 feet away.
