WebNo. 11.2 km/sec is needed to completely escape Earth and start orbiting the Sun. Hence the term "escape velocity." Its the velocity you need to escape Earth's gravity well for good completely and then get into a heliocentric orbit. Real rockets don't go that fast, they just get around 27,000 kmph to get into orbit, which is just around 7.6 km/s. WebLet points A and B be collinear with the center of the Earth. When the satellite is at a distance of a, it's speed is equal to v 0. Calculate the speed of at the satellite a distance b from the focus. So first I approached this by the conversion of mechanical energy: 1 2 m v 0 2 − G m e m a = 1 2 m v b 2 − G m e m b I got,
