This book is a compilation of all the problems publiburned by College Board in AP Physics B and AP Physics C that are appropriate for the AP B level and problems from AAPTs Physics Bowl and U.S. Physics Team Qualifying Exams organized by topic.

The troubles vary in level of challenge and also kind and also this book represents an inhelpful resource for exercise and testimonial and also need to be used regularly. Whether you are struggling or confident in a topic, you should be doing these difficulties as a reinforcement of ideas and principles on a range that could never before be covered in the class time allotted.

The answers as presented are not the only technique to solving many kind of of these problems and physics teachers may present slightly different techniques and/or various symbols and variables in each topic, yet the underlying physics ideas are the exact same and also we ask you review the remedies with an open up mind and also usage these distinctions to expand also your trouble solving skills.

Finally, we are fallible and also if you find any kind of typographical errors, formatting errors or anypoint that strikes you as unclear or unreadable, please let us recognize so we can make the crucial announcements and corrections.

Problems marked with an astethreat (*) are challenging troubles that some would consider to be outside the scope of the course, however depend on the ideas taught within the course or they might require information taught in a later on part of the course. These are for those students who wish to go past the level needed, but are not required for success in the AP B course.

AP Physics Multiple Choice Practice Kinematics

1. A auto travels 30 miles at an average rate of 60 miles per hour and also then 30 miles at an average rate of 30 miles per hour. The average speed the vehicle over the 60 miles is

(A) 35 m.p.h. (B) 40 m.p.h. (C) 45 m.p.h. (D) 10 m.p.h. (E) 53 m.p.h. Questions 2 4

relate to two particles that start at x = 0 at t = 0 and also move in one measurement separately of one one more. Graphs, of the velocity of each ppost versus time are shown below

Pshort article A Pshort article B

2.

Which ppost is farthest from the origin at t = 2 secs. (A) A (B) B (C) they are in the same area at t = 2 secs (D) They are the same distance from the

beginning, however in opposite directions (E) It is not feasible to identify 3. Which pshort article moves via constant non-zero acceleration? (A) A (B) B (C) both A and also B (D) neither A nor B (E) It is not possible to identify 4. Which pshort article is in its initial position at t = 2 seconds? (A) A (B) B (C) both A and also B (D) neither A nor B (E) It is not possible to determine

5. The graph above reflects the velocity versus time for an item relocating in a straight line. At what time after t = 0 does the object aacquire pass through its initial position? (A) Between 0 and also 1 s (B) 1 s (C) Between 1 and 2 s (D) 2 s (E) Between 2 and 3 s 6. A body moving in the positive x direction passes the beginning at time t = 0. Between t = 0 and also t = 1 second, the

body has actually a constant speed of 24 meters per second. At t = 1 second, the body is given a consistent acceleration of 6 meters per second squared in the negative x direction. The position x of the body at t = 11 seconds is

(A) + 99m (B) + 36m (C) 36 m (D) 75 m (E) 99 m

7. The displacement, x, of a things moving along the x-axis is displayed above as a role of time, t. The

acceleration of this object must be (A) zero (B) continuous yet not zero (C) increasing (D) decreasing (E) equal to g

8. A 2-kilogram block rests at the edge of a platform that is 10 meters above level ground. The block is released horizontally from the edge of the platform via an initial speed of 3 meters per second. Air resistance is negligible. The time it will certainly take for the block to reach the ground is many almost (A) 0.3 s (B) 1.0 s (C) 1.4 s (D) 2.0 s (E) 3.0 s

9. A diver initially moving horizontally with speed v dives off the edge of a vertical cliff and lands in the water a distance d from the base of the cliff. How much from the base of the cliff would the diver have landed if the diver initially had actually been relocating horizontally via rate 2v? (A) d (B) d2 (C) 2d (D) 4d (E) cant be figured out without understanding the elevation of the cliff

10. A truck traveled 400 meters north in 80 seconds, and also then it traveled 300 meters eastern in 70 seconds. The

magnitude of the average velocity of the truck was the majority of nearly (A) 1.2 m/s (B) 3.3 m/s (C) 4.6 m/s (D) 6.6 m/s (E) 9.3 m/s
