My calcs say I need about 15 ft-lb energy to accelerate the ball to about 31 ft/sec. The size of the accumulator will determine the final exit pressure on the ball. Of course leakage around the ball is a big variable.

Ah, I misunderstood.
I still think that you should check to see if the valve/hoses will flow enough air fast enough to do what you want. Though I'm still not convinced that an air-cannon is legal.
