Question

Ракете сообщили скорость, направленную вертикально вверх, модуль скорости равен 5 км/с. Станет ли она спутником земли?

Answer 1

нет, т.к она ее скорость меньше первой космической скорости- 7.9 км\с

Answer 2

Can a Rocket with a Vertical Velocity of 5 km/s Become a Satellite of the Earth?

To determine if a rocket with a vertical velocity of 5 km/s can become a satellite of the Earth, we need to consider the requirements for an object to be in orbit around the Earth.

Orbiting the Earth: For an object to be in orbit around the Earth, it needs to have a certain velocity known as the orbital velocity. The orbital velocity depends on the altitude of the orbit and is the speed required for an object to maintain a stable orbit without falling back to Earth or escaping into space.

Escape Velocity: The escape velocity is the minimum velocity required for an object to escape the gravitational pull of the Earth and move into space. It is higher than the orbital velocity.

Analysis: Given that the rocket has a vertical velocity of 5 km/s, we can determine if it can become a satellite of the Earth by comparing its velocity to the required orbital velocity or escape velocity.

Unfortunately, the search results do not provide specific information about the required orbital velocity or escape velocity. However, we can make some general observations based on scientific knowledge.

Orbital Velocity: The orbital velocity required to maintain a stable orbit around the Earth depends on the altitude of the orbit. The higher the altitude, the lower the required orbital velocity. For example, the orbital velocity for a low Earth orbit (LEO) is approximately 7.8 km/s, while the orbital velocity for a geostationary orbit is approximately 3.1 km/s.

Escape Velocity: The escape velocity from the surface of the Earth is approximately 11.2 km/s. This means that an object needs to reach a velocity of at least 11.2 km/s to escape the Earth's gravitational pull.

Based on the given information that the rocket has a vertical velocity of 5 km/s, it is unlikely that it can become a satellite of the Earth. The velocity is significantly lower than the required orbital velocity for any meaningful orbit around the Earth, and it is far below the escape velocity.

Therefore, the rocket with a vertical velocity of 5 km/s is unlikely to become a satellite of the Earth.

Please note that the specific calculations for orbital velocity and escape velocity require more information, such as the altitude of the orbit or the mass of the rocket. Without these details, we can only provide a general analysis based on scientific knowledge.
