A Ubuhagarike:
On Earth the mountain here is about 510 km high (8% of Earth's radius), higher than the International Space Station flies (about 400 km), so the ball starts above almost all of the air. Down in the air, drag would slow and heat the ball long before it reached orbit speed. That is why real rockets climb out of the air first and then speed up sideways.
Sources: planet masses and sizes from NASA/JPL (bodies.json); paths are exact two-body orbits. Everyday speeds are typical round figures: jet airliners cruise at about 900 km/h, and rifle bullets leave the barrel at roughly 0.7 to 1.2 km/s, about 1 km/s for a fast one.
