Suppose that the shot from the cannon results in a path like that of path A in the figure. If the cannon were more powerful, the ball might take a path like B, or even C. Finally, if a powerful enough cannon could be obtained, it could shoot the cannonball so that the cannonball would come back to where it started. It would then be in orbit.
