Orbital rockets use liquid propellants, often liquid hydrogen + oxygen, to get their large mass off the ground. Burning liquid oxygen produces a tremendous amount of thrust. If the total mass of a rocket, payload, and fuel is $$2\times 10^6$$ kg, what is the necessary thrust in Newton's to start the rocket moving from its launch platform?
The acceleration of gravity is $$-9.8\text{ m/s}^2$$ on the platform.
