Today we learned how to add vectors using components. Make sure you practice this skill by doing the homework this weekend!
If you are struggling with the graphical vector problems on Mastering Physics, here are some hints on how to use it (I am still learning, too!). You cannot move the vectors that were given in the problem. You can add unlabeled vectors to the canvas. Use unlabeled vectors to do the addition/subtraction/scalar multiplication. Once you have the graphical addition set up with unlabeled vectors, you can add a labeled vector for the vector that you were trying to find.
