Graphical Solution of Rectilinear-Motion Problems

Let me just say that you guys are awesome, and I thank StevO and the responders for sharing both questions and advice on a solid tough sounding course.
I use graphic solutions to approach problems, just as a way of communicating with myself. I compulsively reach for a pen and paper during conversations too. It may go to show that under the basic 2D -->3D conversion that every model represents, lies the foundation of geometry that we all have in our fingers. Getting that geometry over to the wordy side of the brain is one of the harder part.

With the way some of my latest attempts have come out. I am seriously thinking of setting out to understand Non Euclidean mathematics and trigonometry better.

I spent four count it four hours. On two problems. A student in my class showed up and we talked about one of the problems because neither of us could figure it out. We had it figured out inside of 15-20 minutes together. Then he had to go.
