The Earth is revolving around sun with an angular velocity w in an orbit of radius D and rotating around its own axis with an angular velocity w' . What ios its total kinetic energy?
As earth is a sphere and different particles are at different distances from the axis of the sun , how we can consider the c.m velocity of the earth ? y cant we apply parallel axis theorem to get the answer as 0.5 (0.4MR2+MD2)w2+0.5 (0.4MR2)w'2
