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.
