- Abstract
It is known that the optimal projection angle corresponding to the maximum range of a projectile moving in air is less than 45° for low-power resistance laws such as the linear or quadratic law. We show that this result is valid only for a uniform atmosphere, in which the density of air is a constant. In a more realistic atmosphere, such as an exponential atmosphere, where the air density decreases with altitude, and specially for high-speed projectiles, the optimal projection angle is much greater than 45°.PACS No.: 45.50.Dd
