Description

By suppressing the kinematics of projectile motion, we show that a projectile thrown at 49.50° above the horizontal maximizes the trajectory's perimeter. We also identify two unique projectile angles, 15.5° and 88.9°, that give two different parabolas with identical perimeters and identical areas.
