We would like to compare the angular momentum of Mars about its axis of rotation with that of Earth's. The mass of Mars is 11% that of Earth, with a radius 53% that of Earth, and a rotational period 103% that of Earth. Assuming both planets to be uniform spheres calculate the ratio of the angular momentum of Mars to that of Earth.
A) 6.0 10^{}^{2 }
B) 5.7 10^{}^{2 }
C) 3.2 10^{}^{2 }
D) 3.0 10^{}^{2 }
E) 3.1 10^{}^{2 }
