How are we able to calculate how far we’re able to throw things extremely precisely?

Question

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?

Answer 1

I often think about that when I grab something and NBA 3 point it from across the room. How quickly you not only know how hard to throw, but know quickly based on the object. Is it a crushed can, crumpled paper, a napkin, a flat object, a ball… Brains and muscles are impressive.
