A person is in orbit around the Earth at a distance of 10000 km from its center and wants to leave. How much extra speed does the person need to ensure they can escape Earth's gravity.

e.g. If the orbital speed is 700 m/s and they need to go 800 m/s, enter 100 m/s.

Remember that 1 km=1000 m.

The mass of the Earth is 6E24 kg.

The gravitational consant (G) is 6.67E-11 Nkg^2/m^2
