For example, if you’re standing 20 feet away from me, and you tell me to throw you a ball, how is my arm able to generate almost the exact amount of power required to throw the ball 20 feet? How and where does this “calculation” happen?

There are circuits in the brain that do all sorts of specialized tasks. Humans have a sense called proprioception. It’s how you can feel where parts of your body are without having to look at them. It’s the circuit a guitarist might use when playing but not staring at the fretboard.
There are similar systems for things like judging a throw. Our brain is accustomed to handling objects and feeling their mass. We’re used to seeing what happens when they fall or hit something else. We become familiar with how things behave and how our body moves.
I’m not sure even a neuroscientist would be able to explain exactly what’s going on in the brain to accomplish it, we’re still learning. It’s sufficient to say that our neurons connect in a certain way to each other and those connections somehow enable us to perform actions like judging a throw.
