Estimate the kinetic energy of the Earth with respect to the Sun as the sum of two terms,
(a) That due to its daily rotation about its axis, and
(b) That due to its yearly revolution about the Sun. |Assume the Earth is a uniform sphere with mass = 6.0 x 1024 kg and radius = 6.4 x 106m, and is 1.5 x 108 km from the Sun|
