Two concentric dashed circles represent the initial and final orbits of a satellite around a central planet. The inner circle is labeled with radius R and the outer circle is labeled with radius 9R. A small dot representing the satellite is shown on the inner circle with a velocity vector tangent to the path.
Transition of a satellite from a circular orbit of radius R to a radius of 9R.
A satellite of mass \(m\) is in a stable circular orbit of radius \(R\) around a planet of mass \(M\). The satellite has an orbital angular momentum \(L\) relative to the center of the planet. The satellite’s engines are fired to transition the satellite into a new stable circular orbit of radius \(9R\). Which of the following is a correct expression for the new orbital angular momentum \(L_{new}\) and a correct justification for that expression?
