Question
What is the escape velocity from the surface of the
Earth?Solution
Escape velocity ve = √2gR, where g = 9.8 m/s² and R = 6400 km. Calculating this gives approximately 11.2 km/s. This is the minimum speed needed for an object to escape Earth’s gravitational field without further propulsion.
