HW 3 is now ready to go.

I just finished setting up HW 3, which goes over some of the concepts in our computation of the acceleration of skateboarder Alan in Thursday's lecture. It also refers to the data set, which I typed up and posted - so that you can double check your own lecture notes.

Skateboards

Bring your skateboard to lecture for the next few lectures. We will need visible velocity that can be measured.
