Two boats are anchored in the harbor, separated by a horizontal distance of 24 m. The boats bob up and down as waves enter the harbor. When one boat is at its highest point, the other is also at its highest point and there is one wave crest between them. Each boat makes exactly 6 complete up-and-down cycles every 36.0 s. The vertical distance between a boat's highest and lowest position is 2.4 m. Determine the wavelength (m), frequency (Hz), period (s), amplitude (m), and speed (m/s) of the waves.
