Homework Statement
The polar ice caps contain about 2.3x10^19 kg of ice. This mass contributes essentially nothing to the Earth's moment of inertia becuase it's located near the poles. Estimate the change in the length of one day if the caps were to melt and redistribute evenly over the Earth's surface.
