The Initial Velocity
If the projectile is launched with an initial velocity v0, then it can be written as
- .
The components v0x and v0y can be found if the angle, ϴ is known:
- ,
- .
If the projectile's range, launch angle, and drop height are known, launch velocity can be found by
- .
The launch angle is usually expressed by the symbol theta, but often the symbol alpha is used.
