A passenger walks from one side of a ferry to the other as it approaches a dock.Passenger's velocity is 1.50 m/s due north relative to the ferry, and 4.40 m/s at an angle of 30.0 west of north relative to the water.
What is the magnitude and direction of the ferry's velocity relative to the water?
v = m/s
angle = degrees west of north
