Magnitude and direction

  1. Oct 11, 2005 #1
    I just can't figure out how to determine the magnitude and direction of the wind's velocity with this information, the combinasons of possibilities seem endless.

    An airplane travelling at a cruising velocity of 1000 km/h is headed south toward a destination of 1500 km away. In order to maintain its southward heading, the airplane must travel on a course [S15°W].

    Determine the magnitude and direction of the wind's velocity.


    Thanks in advance

    Hint: Try drawing a diagram of the velocity vectors on a coordinate system to visualize what's going on.

    I'm coming up with 261 km/h [E7,5°S]

    I'm not too sure about this answer though, can anyone tell me if i'm right or not?

    add two of the vectors and see if you come up with the third

    I'm not too sure why they give you the 1500km away, unless theres more to the question. I'm sorry if my diagram is rudimentary.
