Air speed

  1. Sep 8, 2010 #1
    An airplane normally flies at 260 km/h.
    a) What is its air speed if it experiences a
    60 km/h headwind?
    Answer in units of km/h.

    b) What is its air speed if it experiences a
    60 km/h tailwind?
    Answer in units of km/h.

    I don't know how to solve this.

    You must add the vectors for air speed and wind speed. Each vector is an arrow. You place the arrows head-to-tail and the sum is the new vector going from the beginning to the end of the head-to-tail series. Check out

    Note that your problem is simpler because the two vectors you add in each part are in the same or opposite directions, no angles involved.
