Calculate the kinetic energy of a spherical asteroid due to its daily rotation about its axis in a geostationary orbit around Earth. Assume the asteroid has a mass of 1.2$\times$10¹³ kg and is located at an altitude of 3.6$\times$10⁴ km above the Earth's surface. The radius of the asteroid = 2.4$\times$10³ m.
