How to calculate where an object will hit the floor with the applied force

Hi, so in my game I have an enemy and I want him to throw a GameObject in the direction of the player, but the force needs to be applied with some angle directed up. This GameObject should move in three axis but end at the position of the player. I want to achieve something like on the image in the attachment but I don't even know where to start, how to calculate what force I should apply to the throwable GameObject? This object should move with constant speed.

You need to select an initial velocity, depending on your application, this could be fixed or you could iterate the linked approach until you are in range. This assumes you do not have any drag forces acting on your projectile, it will all get much more complicated if you do, so I recommend you avoid that.
