Question:

(a) Assume Earth is a uniform solid sphere. Find the kinetic energy of Earth due to its rotation about its axis.

(b) Suppose we could somehow extract 1.0% of Earth's rotational kinetic energy to use for other purposes. By how much would that change the length of the day?

(c) For how many years would 1.0% of Earth's rotational kinetic energy supply the world's energy usage (assume a constant 1.0 × 10²¹ J per year)?
