For Quiz 5 I will ask for revisions on #3, the final problem. There are some things I particularly want to see: a Newton’s Second Law analysis (do not use work and energy methods!), and careful justification of each equation you use (for instance, n=mg turns out to be true, but how do you know this is the case in this problem?). You need to draw a proper free-body diagram and use it in your solution.
To aid in the revisions (which I remind you are not merely corrections) I have developed a template you can use to guide your reasoning. This is in the program handouts for Physics on the fileshare as well as this post. Quiz 5 is also included in both locations. Use of this template is optional, but recommended if you are struggling with the format I am requesting for revisions.
If you have old quizzes (Quiz 2-4) and have not submitted revisions for those, please do feel free to submit them late. This is a great opportunity to demonstrate your learning and understanding, no matter your performance on the original quiz.
