The Moon is tidally locked with Earth, which means that it spins on its axis exactly once each time it orbits our planet. Because of this, people on Earth only ever see one side of the Moon. We call this motion synchronous rotation.
WebA satellite is placed in an elliptical orbit around the Earth with an eccentricity of 0.5 and a semimajor axis of 10,000 km. Calculate its radial distance (in km) from the Earth, its eccentric anomaly, and its orbital speed (in m/s) when its true anomaly is 60°. Calculate its mean motion constant.
