Consider a rocket of mass m directly heading upwards, out to space. What is the escape velocity vo at which the rocket needs to start to reach space, without getting pulled back to Earth? The mass of the Earth is M, and its radius is R. 2Gm R O Not enough information, requires final position of rocket. 2GM 2Gm Vo = R.
