Vector Displacement calculation

  1. Sep 27, 2015 #1
    • Member warned to use the formatting template
    An airplane takes off and flies 245 km on a course of 45.0° south of west and then
    changes direction and flies 175 km due south, where it lands. Find the displacement
    from its starting point to its landing point.

    I have literally no idea how to approach this, I worked with physics only sparingly in my homeschooling, and I need help figuring out the approach to this type of equation. I'm a quick learner though!

    Why don't you make a sketch of the plane's travels? With a picture, that may give you some ideas on how to tackle this problem.

    Right triangles off of each vector to the x/y lines?

    If that's what your diagram shows. Trig is usually helpful in solving these types of problems.
