Estimate the ratio of their orbital kinetic energies

Reference no: EM13550662

The days on Mars and Earth are of nearly identical length. Earth's mass is 9.35 times Mars's mass, Earth's radius is 1.88 times Mars's 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 Earth's year. Assume that they are both uniform spheres and that their orbits about the Sun are circles. Estimate the ratio (Earth to Mars) of the following.

(a) their spin angular momenta

(b) their spin kinetic energies

(d) their orbital kinetic energies.
