Question

Helen is standing at the sea’s edge watching a ship disappear in the distance. The sea is calm. The ship vanishes hull first, then masts and sails. Helen understands that this is a sign that the Earth is curved. She knows that the height of the ship is 15 m above the sea level and the elevation of her eyes above the sea level is 1.7 m. Determine the distance from Helen’s eyes to the top of the ship’s mast at the moment of ship’s disappearance. Suppose that Earth is perfectly spherical and its radius is 6 378 km.
