OK - you don't have any homework due tomorrow, just the force table lab. I suggest you know how to do the drawing.
I took some time to do this example. STUDY IT!! Duplicate it, if you need to.
Also, I suggest that you do this worksheet I wrote for my Regular Physics students. Most of them feel very good about vectors, now.
