How do I make an object instantly drop to the ground (skipping the fall animation)?

Now, I have an object wherein I only know the x and z position. If I place it at a very high y coordinate, I would get an animation of it falling down towards the ground. I want to skip this and instantly make it be on the ground. How do I do that?

I asked stackoverflow for the answer How do I make an object instantly drop to the ground (skipping the fall animation) in Unity? - Stack Overflow

Turns out I have to use Raycast to get the position on the ground.
