Part A Calculate the magnitude of the angular momentum of the Mars in a circular orbit around the sun. The Mars has mass 6.42×1023kg , radius 3.40×106m , and orbit radius 2.28×1011m . The planet completes one rotation on its axis in 24.5 hours and one orbit in 687 days.
Part B Calculate the magnitude of the angular momentum of the Mars due to its rotation around an axis through the north and south poles, modeling it as a uniform sphere.
