Estimate the kinetic energy of the mars with respect to the sun as the sum of the terms, that due to its daily rotation about its axis, and that due to its yearly revolution about the sun. [assume the mars is a uniform sphere with mass = 6.4×1023 kg , radius = 3.4×106 m , rotation period 24.7 h , orbital period 686 d and is 2.3×108 km from the sun.]
