Homework Help: Relative velocity

  1. Sep 7, 2004 #1
    Ship A travels at 3m/s due NE, ship B travels at 2.6 m/s in direction S30E.
    a. What are the magnitude and direction of the velocity of ship A relative to ship B?
    b. After what time will they be 140m apart?

    I have found the answer to be 4.45m/s
    But I don't know whether it is true...and I am not sure of its direction.
    Please help. :frown:

    you can use the components of that vector you figured out to get the direction.
