Hello. Collectively, you did fairly well on the first test. The grades will be posted on Vista before the end of the day (Monday). Everyone in the course (M. 151) got an extra 8 points. The grade you will see in Vista ALREADY INCLUDES these 8 points. The reason is that the faculty decided, after looking again at the textbook, that the "falling car" question was premature; Stewart has not yet discussed what acceleration is or how to calculate distance from acceleration. About half of you already understood the question on the basis of prior information (from physics courses or wherever), so in effect you got double credit on that problem. -- Stephen A.
