In 2006, police discovered her notary commission had expired and her seal had been confiscated by the Department of State. Yet she continued to pass herself off as a commissioned Pennsylvania notary, going so far as to use notary seals from other people. Lint was sentenced to one to two years in prison.
If a rocket is launched from the surface of the Earth, it needs to reach a speed of at least 7.9 kilometers per second (4.9 miles per second) in order to reach space.This speed of 7.9 kilometers per second is known as the orbital velocity, it corresponds to more than 20 times the speed of sound.Â© GFDL.he 'second cosmic velocity' is the so-called escape velocity from the Earth: 11.2 kilometers per second. This is the speed a rocket should attain in order to be able to escape from the Earthâs gravitational field and fly to other planets.
This is the speed a rocket should attain in order to be able to escape from the Earthâs gravitational field and fly to other planets. It follows from the laws of orbital mechanics that the escape velocity (11.2 km/s) is equal to the orbital speed (7.9 km/s) multiplied by 1.414 (i.e. by the square root of 2).he 'third cosmic velocity' is the speed that a spacecraft needs to attain in order to be able to leave our solar system. This solar system escape velocity is about 42 kilometers per second (or 0.014 percent of the speed of light in a vacuum). Again, this is the product of the orbital velocity and the square root of 2.
