Question

an earth satellite is observed at perigee (the orbit point closest to the earth) to be 250 km above the earth's surface and travelling at about 8500 m/s. find the eccentricity of its orbit and its height above the earth at apogee (the orbit point farthest to the earth). use that the earth's radius is re ~ 6.4e6 m.

Answer 1

The question requires knowledge of orbital mechanics and the conservation of angular momentum to find the eccentricity and height at apogee of a satellite's orbit. However, the provided information is insufficient to calculate a precise answer.

Step-by-step explanation:

The question involves applying principles of orbital mechanics to find the eccentricity of a satellite's orbit and its height at apogee, given its speed and altitude at perigee and its speed at apogee. This involves knowing the Earth's radius and employing the conservation of angular momentum and the conservation of mechanical energy within the two-body problem context.

Due to insufficient information provided directly about the eccentricity and lack of complete data about the satellite's energy at apogee or perigee in the provided example, it is not possible to accurately calculate the eccentricity of the orbit or the height at apogee based on the given question's data.
