Find the length of one day if the polar ice caps melted

  1. Apr 19, 2012 #1
    1. The problem statement, all variables and given/known data
    The polar ice caps contain about 2.3x10^19 kg of ice. This mass contributes essentially nothing to the earths 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 earths surface.

    2. Relevant equations

    SA of a solid sphere=4pir^2
    inertia of a solid sphere=2/3MR^2
    inertia of a shell=2/3MR^2

    3. The attempt at a solution
