Ejection velocity squared  as a function of trigger velocity , for small balls and n = 5. Each circle corresponds to one ejected ball. The linear relation is a general feature, regardless of choice of ball size and n. Chained cannon: When the cannons are coupled together, the speed squared follows a convergent series, represented by the green dashed line. With a large number of cannons, the final speed corresponds to the purple intersection cross.
