Recent announcements:

  • Exam grades are on moodle. Please double check that your exam grade matches what is on moodle. Please ignore the overall course grade on moodle. I'm just not sure what algorithm it uses when some grades (like the Final exam and HW) are missing.
  • We will continue to use Vol II of the same textbook from last semester. Physics for Scientists and Engineers by Randall Knight. 4th ed. Vol 2.

STEM Center Physics Tutor Hours:

  • Mondays 2-­5 and 6­-9 PM
  • Tuesdays 5­-9 PM
  • Wednesdays 4­-6 and 7-­9 PM
  • Thursdays 5­-9 PM
  • Sundays 6-­9 PM

All problems are from Knight unless stated otherwise. Problems in regular type are the same ones that will appear in MP. Problems in bold type are ones that will NOT appear in MP, and you will turn them in to me.
