A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. It takes a time of 2.00 for the boat to travel from its highest point to its lowest, a total distance of 0.68. The fisherman sees that the wave crests are spaced a horizontal distance of 5.60 apart.
How fast are the waves traveling?
What is the amplitude of each wave?
A large mountain can slightly affect the direction of "down" as determined by a plumb line. How far would the lower end move toward the sphere
