# Calculate orbital angular momentum

ssarpal
Homework Statement:
A satellite of mass M kgs has an elliptical orbit of T hours around the Earth with ##Rmax = N * Rmin##.
At one instant, the satellite is at a distance D meters from center of Earth and moving at V km/s.

Q) Find the orbital angular momentum.
Relevant Equations:
L = r * m * v * sin θ
The section Kepler’s Second Law here describes the above equation.

In this problem,
##\text{r = D, m = M and v = V}##

What is the way to go about finding out ##\theta## as shown in Figure 13.21?
