Judy,

        I do not use calculus in my first level physics courses.  If I
were to do this I would cut my classes in half.

Now about vectors.  For beginning ideas, I use component vectors.  Why
make it difficult for students.  When we are working with non-right
triangles we do move into the Law of Sines and Law of Cosines.  If I
recall, PSSC pushed accurate drawings further reducing the math.  Not a
bad place to start and then work toward the more abstract math approaches.

From what you said in your message, you are not on the wrong track.
