Problem: A passenger walks from one side of a ferry to the other as it approaches a dock. Passenger's velocity is 1.55m/s due north relative to the ferry and 4.60m/s at an angle of 30.0 degree west of north relative to the water,
Part A: What is the magnitude of the ferry's velocity relative to the water?
Part B: What is the direction of the ferry's velocity relative to the water?
Please help for the above problem, completely confused!! Show each steps if possible, Thanks.
