(a) Calculate the rotational kinetic energy (in J) of Saturn on its axis. (Assume its mass to be 5.69 x 1026 kg, the period about its axis to be 10.2 h, and its diameter to be 1.21 105 km.) J (b) What is the rotational kinetic energy (in J) of Saturn in its orbit around the Sun? (Assume its distance from the sun to be 1.43 x 109 km and its period about the sun to be 10800 days.)
