Exam 1 supplemental
I've posted the scores for the extra credit portion of exam 1; add this to your original score and that's your exam 1 grade, out of 100.
They seemed to go much better than the equivalent problem on the exam. I hope this gave some people a chance to solidify their understanding of 2D kinematics.
The class average was about 14 out of 24; this sounds low, but I graded these fairly strictly, unlike the exam which was graded fairly easily. This brings the class average up to about 75, which is where it should be.
