# Projectile Launch Angle

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

## Projectile Launch Angle formula

 $$\large{ \theta = \frac{ 1 }{ 2 } \; sin^{-1} \left( \frac{ g\; d }{ v_0^2 } \right) }$$

### Where:

$$\large{ \theta }$$ = angle of the initial vertical from x-axis

$$\large{ g }$$ = gravitational acceleration

$$\large{ d }$$ = horizontal position

$$\large{ v_0 }$$ = launch velocity
