Formula to find Distance from Exit Velocity and Launch Angle
Hi Experts;
I've tried researching via google and have come up short.
I need assistance with a formula to predict the distance of a projectile.
I have the exit velocity and the launch angle.
I am writing in C#, but am new to it. Mostly, what I need is just a formula.
For extra credit :), I eventually will need to predict the max height of the projectile (using EV, LA and predicted Distance).
Thank you!

Projectile Motion
Basic Equations and Parabolic Path
- Projectile motion is a form of motion where an object moves in parabolic path; the path that the object follows is called its trajectory.

Hi David;
As I research farther I found I definitely need to include gravitational force (or any >0 angles will never come back to earth). I'm working on how to find/apply that value.
Regarding wind, humidity we've determined we can accept results without those variables. My function is limited to 500 ft (baseball stadium). This may also eliminate the need for initial and terminal elevation as the field is flat. But I admit I'm not sure what those terms are referring to (from mountain to sea or bat contact to ground (approx 24 inches)).
I appreciate the link. I'll study.
Thank you.

Hi Paul ~
Excellent info. Thank you!
Excellent info. Thank you!
Once the projectile is launched, it experiences a constant downward acceleration of 32 ft per second squared. This downward acceleration due to gravity is what makes the projectile fall towards earth.

Hi All;
Thank you very much for the information and references. I spent days studying projectile motion and the ways to calculate range, height and hang time.
Unfortunately, the approach shifted from actual calculations to pre-set data from a table generated from our known data.
Instead we are querying out 'if exit speed >= x and launch angle >= y; result = n'.
None the less, the resources and study are worth it knowing the approach we're starting with will most likely need to be perfected in the future.
Thank you again!
