- Homework Statement
- We were asked to calculate earth's escape velocity using methods 1) Newton law of motion, 2) Conservation of energy, 3) Lagrange method.
As to conservation of energy, that is clear, and I got the result (ca. 11.19km/s).
However for 1) and 3) I have no Idea, though I might have a start for 3).
Help would be appreciated.
Thanks
