Maximum Range
Suppose a cannonball launched from a cannon at 3 various launch angles - 30-degrees, 45-degrees, and 60-degrees. The launch speed is held constant; just the angle is modified. Suppose as well in which the cannonballs do not encounter an important amount of air resistance. The animation below depicts such a conditions. The path of the cannonballs are shown. Further, the velocity elements (horizontal and vertical) are represented through arrows within the animation.
