The mass of the earth is M = 6.0 x 1024 kg and its radius is R = 6.4 x 10° m. (a) Estimate the rotational kinetic energy of the earth, in joules (J). (b) The world's annual power consumption is about 20 TWh. If the earth's rotational kinetic energy could be converted to electrical power, how long could it supply energy to the human race, assuming our power consumption remained constant? Report your answer in seconds and in years.
