PHYS 102 Spring 2008 Exam #1 Study Guide These are the equations and instructions that will appear on the first page of the exam: THE ONLY ITEMS YOU MAY USE DURING THE EXAM ARE A WRITING INSTRUMENT AND CALCULATOR. PLEASE SILENCE AND PUT AWAY YOUR CELL PHONES! Equations Kinematics (constant acceleration) x = x o + v ox t + 1 2 a x t 2 v x = v ox + a x t v x 2 = v ox 2 + 2 a x ( x x o ) y = y o + v oy t + 1 2 a y t 2 v y = v oy + a y t v y 2 = v oy 2 + 2 a y ( y y o ) Projectile Motion a x = 0 a y = g Dynamics F x = ma x F y = ma y W = mg f s μ s n f k = k n F spring = k Δ x For the free-response items on this exam, 11-13, you must clearly show your work, starting from one or more of the equations above, in order to earn credit for your response. Numerical answers without any supporting work will receive zero credit, even if they are correct. Numerical answers must include units!!
