Hello,

I'm trying to simulate a projectile movement (without any air friction). But my projectile parameters are not conventional.

I know :

I need to find :

So basicly I'm trying to find the formulas that give θ and g according y0, v0, d, h.

And that's where I'm stuck :)

Here is an image to be a bit clearer :

Any help is welcome

Thanks !

I'm trying to simulate a projectile movement (without any air friction). But my projectile parameters are not conventional.

I know :

- The initial height (y0)
- The initial velocity (v0)
- The maximum horizontal travel distance (d)
- The maximum height (h)

I need to find :

- the initial angle (θ)
- the gravity (g)

So basicly I'm trying to find the formulas that give θ and g according y0, v0, d, h.

And that's where I'm stuck :)
