A-) Determine the angular momentum of Mars about its rotation axis (assuming Mars is a uniform sphere). Mars has a mass of 6.4×10^23 kg, a radius of 3.4×10^6 m, a rotational period of 24.7 hours, an orbital period of 687 days, and is 2.3×10^8 km from the Sun.
B-) Determine the angular momentum of Mars in its orbit around the Sun (treating Mars as a particle orbiting the Sun).
