A passenger walks from one side of a ferry to the other as it approaches a dock.Passenger's velocity is 1.45 m/s due north relative to the ferry, and 4.50 m/s at an angle of 30.0º west of north relative to the water.
What is the magnitude and direction of the ferry's velocity relative to the water?
I tried to set the guy walking north (90º) and the other vector at 120º because that is 30º west of north. Now I try to find the magnitude of that and I keep getting 5.8 and I get a direction of 22.8º West of north.
I have plugged these values into my "mastering physics" homework deal and they come up wrong. I have tried my equations looking at the exact problem with different numbers but it had a solution and I still could not come up with the solution they got so obviously my methodology is off somewhere.
please help. thank you.
