Estimate the kinetic energy of mars with respect to the sun as the sum of two terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. (assume mars is a uniform sphere with mass = 6.4Ć10 to the power of 23 kg, radius = 3.4Ć10 to the power of 6 m, rotation period = 24.7 hours, orbital period = 686 days and is 2.3Ć10 to the power of 8 km from the sun.)
