The days on Mars and Earth are of nearly identical length. Earths mass is 9.35 times Marss mass, Earths radius is 1.88 times Marss radius, and Mars is on average 1.52 times farther away from the Sun than Earth is. The Martian year is 1.88 times longer than Earths year. Assume that they are both uniform spheres and that their orbits about the Sun are circles. Estimate the ratio (Earth to Mars) of (a) their spin angular momenta, (b) their spin kinetic energies, (c) their orbital angular momenta, and (d) their orbital kinetic energies.
