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.
As it continues to be pushed by sunlight, the solar sail-propelled vehicle will build up speeds that rocket powered vehicles would never be able to achieve. Such a vehicle would eventually travel at about 56 mi/sec (90 km/sec), which would be more than 200,000 mph (324,000 kph).ooner or later, no matter how fast it goes, the rocket ship will run out of power. In contrast, the solar sail craft has an endless supply of power from the sun. Additionally, the solar sail could potentially return to Earth, whereas the rocket powered vehicle would not have any propellant to bring it back.
