Hi. My question is this: If the sail of a ship were a 100 ft. tall and you were a mouse at the edge of the shore looking out at it, how far out would the ship be when it disappears? ( your eye level is level with the water.)

Thank you!

Hi Stacy,

We had an earlier question on the Curvature of the Earth and in our reply there was a calculation to show that the earth curves approximately 8 inches per mile. How many miles would give a curvature of 100 feet?
