(a) What is the rotational kinetic energy of the Earth
Chapter 10, Problem 76(choose chapter or problem)
(a) What is the rotational kinetic energy of the Earth about its spin axis? Model the Earth as a uniform sphere and use data from the endpapers of this book. (b) The rotational kinetic energy of the Earth is decreasing steadily because of tidal friction. Assuming the rotational period decreases by 10.0 ms each year, find the change in one day.
