Homework Assignments for PHY-252 Spring 2005 About 98% of all Homework assignments are to be completed using Mastering Physics (MP). You may expect approximately 7 Mastering Physics HW problems per lecture. You can only find the Mastering Physics problems at masteringphysics.com. The due dates for all Mastering Physics assignments will be posted on your Mastering Physics assignment list. Approximately 2% of the HW problems will have to be written up and handed in at recitation. You will find those problems, along with due dates, on this web page. Each HW assignment should be worth a total of 50 points; so if the Mastering Physics part of an assignment is worth less than 50 points, check here to find the problem which must be written up and handed in.
