Okay, even if I can't think about a formula to apply, do I need to be qualified to understand that a Boeing 747 will fall to the ground while trying to make a turn at 1000 ft while the speed is only 250 mph? It's called common sense, isn't it? On the contrary, I've seen many instances in my life...

Okay, let's simplify the problem. What speed is required to throw a 1500 kg container from the sea level up into air to reach 160 km altitude and then fall down? I just want to see some numbers without getting too deep into efficiency, orbit, etc. Think about a 1500 kg container being...

SpinLaunch is just another scam project that exists only because investors and sponsors have no idea about physics. Just like Mars One, SpinLaunch will cease to exist pretty soon without launching a single satellite, and sponsors will just lose all invested capital.

The direction of the velocity is perpendicular to Earth's surface. And by initial speed I mean a sudden thrust, after which there's no thrust at all.

I just wanted to know the initial speed required to launch 1500 kg into 160 km orbit and that cargo should still have velocity of 7.8 km/s after reaching 160 km altitude. Does anyone know the proper formula? This is what AI gives me: To throw a 1 kg object into a 160 km orbit from sea level...

Just wanted to see the calculation of this theory with a 1500 kg egg-shaped container without trying to improve it or make it look real.

Thank you! Yes, and that's why my question is what the initial speed should be. I know it is impossible, just a theory. But I would like to know the initial speed that isn't going to be applied all the way, but only at launch time.

Let's say we have an egg-shaped (for better drag) 1500 kg cargo container and a acceleration system that accelerates that container and launches it at sea level to reach 160 km on its own without any engine. What speed should be applied to this 1500 kg container at sea level, so it reaches 160...
