Careful now, the Human Cannonball is counting on you to make your calculations accurately. Otherwise he'll end up flat as a pancake and you'll end up with 0 points or a miss to show for it! The objective of this game is to shoot the man out of the cannon and into the water tower. To accomplish this, you must consider the following variables:
The angle of the cannon (establishes the line or arc of trajectory the man follows after being shot from the can- non).
The speed (MPH) at which the man travels after being shot from the cannon.
The distance between the cannon and the water tower.
