All exams prior to 2015 are AP Physics B exams. Each question is labeled by the year of the exam, the test, and the question number on the actual AP exam. Solutions for many of the previous AP Exam problems are available online. Parts of some questions have been removed if they pertain to content we have not yet covered. Please note that the AP Physics 1 exam is significantly more conceptual than the AP Physics B exam, thus supplemental conceptual questions have been added to some AP Physics B questions. For all AP Physics B problems, in addition to completing the required math, students should be able to explain in words their solutions and the logic behind their steps. 1994 AP Physics B Q1 a) Removed: requires physics content beyond Unit 3 b) Determine the time it takes for the ball to reach the plane of the fence. c) Will the ball hit the fence? If so, how far below the top of the fence will it hit? If not, how far above the top of the fence will it pass?

These data points are also plotted on the graph. a) On the grid above, sketch the smooth curve that best represents the student’s data. 7 Some content copyright © 1984-2024 by College Entrance Examination Board.

Past studies have shown that runners in such a race accelerate uniformly for a time tu and then run at constant speed for the remainder of the race. A world- class runner is visiting your physics class.
