First of all I want to let you know that I'm not a Physicist, I am a Video Game Developer. I can simulate physical and mathematical equations and can also use some built in physics.
For example I can move an object through parametric equation of projectile
$$x = vt\cos\theta$$ $$y = vt\sin{\theta} - \frac{1}{2}gt^2$$
I can get values by increasing time, $t = 0$,$ t = 1$, . . . So these values make a good projectile.
On the other hand if I use built in Physics of Game Engine then I have to only Apply some force with a 2d or 3d vector. For example I can apply force of $\vec f = 24,15,6$ with other things in hand and I can change it like mass, gravity.
So now my question is that how can I calculate $\vec f (second method)$ or $data$ to populate in first method that the body will land on a specific predefined point.
- I'm repeating the objective is to launch a projectile such that it will land on a specific predefined point?
