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 10⁶ m, and is 1.5 x 10⁸ km from the Sun.
