1 Physics 202 Final (Monday, December 12) Fall 2016 (Saslow) White Version Name (printed) Lab Section(+2 pts) Name (signed as on ID) Show all work. Partial credit may be given. Answers should include the correct sign and the correct units. Total points will be scaled to 100. If your grade on the final exceeds that on your lowest exam, that exam grade will be replaced by the average of that exam and the final. Look at front board for any corrections. 1.
