A passenger walks from one side of a ferry to the other as it approaches a dock. If the passenger's velocity is 1.70 m/s due north relative to the ferry, and 4.5 m/s at an angle of 34.0° west of north relative to the water, what are the direction and magnitude of the ferry's velocity relative to the water?
