Math Problem Statement
A satellite is launched with the following conditions: (r_{0} * v_{0} ^ 2)/mu = 3 beta_{0} = 10 ^ 0 where r_{0} v_{0} beta_{0} denote the magnitude of the radius (position) vector, orbital speed, and flight path angle, respectively. The perigee radius of the orbit is 9000 km. The eccentricity of the orbit is (where R = 6400 km and mu = 398601k * m ^ 3 / (s ^ 2) ) a) 1.318 b) 0.629 c) 1.977 d) 1

We can calculate the value of eccentricity using the relation between the perigee, apogee, and the semi-major axis.
Let's calculate the eccentricity numerically.The solution for eccentricity based on the given relation is:
Next, we need to find using the provided condition . Since , we can substitute this into the equation for eccentricity.
Let’s compute using the known parameters and then calculate the corresponding eccentricity value.It seems that the assumption km results in an eccentricity of , which indicates a circular orbit. However, given the context and the provided options, this outcome doesn't match any of the choices provided.
Let's take into account that the orbital speed isn't directly tied to , and re-calculate the eccentricity assuming a different corresponding to a non-circular orbit.
