1. A stationary boat in the ocean is experiencing waves from a storm. The waves move at59km/h and have a wavelength of 160m. The boat is at the crest of a wave. How much time elapses until the boat is first at the trough of a wave? Express your answer to two important figures and include the appropriate units.
2. In the deep ocean, a water wave with wavelength 95 m travels at 12 m/s. Assume a small boat is at the crest of this wave, 2.0m above the equilibrium position. What will be the vertical position of the boat 3.0s later? Express your answer to two important figures and include the appropriate units.
