crests that are 15 meters apart, and they are gently rocking the boat once every 5 seconds. you decide to lift the
anchor and begin trolling slowly to the west at 2.0 meters/second. in 1-2 sentences, explain the strategy for
calculating how often the wave crests will rock the boat in this situation based on your investigation.
