If they melted and water was evenly distributed all over the earth.
From what I guess I should use angular momentum. Ang momentum = I (moment of intertia) X W (angular velocity)
I = mr^2 for a thin hoop...I think I use this for the ice caps
and I for a uniform sphere is 2/5mr^2
so since the uniform sphere will make the angular momentum less, the Earth will turn slower and the day will be longer?
does this sound right? or do the two angular momentums need to be set equal to each other? am i on the right track? thanks
