What's the speed of escape from Earth?

Now let me tell you what the speed of escape from the Earth is, and I'm happy to help you. What the speed of flight is, is the second cosmic rate, 11.2 km/s. As long as the object reaches 7.9, it can go around the Earth. At 11.2, it can escape the Earth's gravity. So the elliptical orbit around the Earth is between 7.9 and 11.2.

v1 = 7.9 km/s. The first cosmic velocity is divided into the minimum launch speed of a spacecraft and the maximum operational velocity of a spacecraft. In some cases, when a spacecraft is operating at the first cosmic velocity, it means that the spacecraft is operating along the Earth's surface. It can be calculated by mechanics   v1 = 7.9 km/s.

When a spacecraft operates at the first cosmic speed, it means that it follows the surface of the Earth. Mechanical theory makes it possible to calculate v1 = 7.9 km/s. In fact, there is a dense atmosphere on the surface of the Earth, and it is impossible for a spacecraft to get close to the surface of the Earth for circular motion, which must be at 150 km of altitude in order to move around the Earth.

Three major cosmic velocity-related elements: 1. When a spacecraft reaches a certain value above the first cosmic velocity v1, it becomes an artificial planet orbiting around the Sun from the Earth's gravitational field, which is the second cosmic velocity, also known as the velocity of the velocity of the velocity of the velocity of the velocity of the velocity of the velocity of separation, which is actually no less than 10.848 km/s.2 The minimum launch speed required to launch a spacecraft from the Earth's surface, fly out of the solar system and roam into a vast galaxy is the third cosmic velocity, also known as the escape rate, which can be calculated by force theory at the third cosmic velocity V3 = 16.7 km/s.

Let us say here how fast we are fleeing the Earth. Thank you for reading this paper. More information on how fast we are fleeing the Earth can be found at this station.
