# Projection (angle, height and distance)

## Calculates the initial angle, maximum height and travel distance of the projection from the initial velocity and flight duration.

Initial velocity v
 m/s km/h fps mph
Flight duration t
 sec
[ Gravity g
 m/s2 ]

Initial angle θ
 deree
Maximum height h
Travel distance l

 $\normal Projection\\(1)\ l=\sqrt{v^2-({\large\frac{gt}{2}})^2}t\\(2)\ h={\large\frac{gt^2}{8}}\\(3)\ \theta=\tan^{\tiny -1}{\large\frac{4h}{l}}\\$
