Materials:      

A composition notebook for daily work, and homework problems A small amount of college ruled paper A scientific graphing calculator (TI-83, TI-84, etc.) A clear plastic metric ruler Pencils (NO PENS!) to be brought to class every day (mechanical pencils preferred) USB Flash drive (for downloading online physics information)

You have embarked upon a wonderful adventure! You have made a great decision and a powerful commitment in taking AP Physics 2!! This summer assignment has a two-fold purpose:  

First, to decrease the amount of new material that you will have to master during the school year for the AP Exam in May 2018. Second, to present an opportunity for you to earn some early strong grades as you begin the first quarter with confidence.

AP Physics 2 Summer Assignment: 2017 1. Download the summer textbook (College Physics from OpenStax College), and the bound quadrille notebook. These items will make the summer assignment easier and clearer. 2. Review the Chapters 1-8. This is a Mechanics review. Please complete the summer assignment – DON’T WAIT UNTIL THE LAST MINUTE!! 3. A problem quiz that will cover the 1st semester of Honors Physics (Mechanics) will occur during the second week of class. You will be able to use your notes. 5. Another attachment to this summer assignment is the IN-CLASS EXAMPLE PROBLEMS to complete. The IN-CLASS EXAMPLE PROBLEMS are included in this packet. The most important thing in this problem assignment is your completely worked-out solutions. The problems will be graded on your worked out solutions. Incomplete or absent work = NO CREDIT! Show me ALL the steps! 6. All the worked-out solutions to the IN-CLASS EXAMPLE PROBLEMS are due the first day of class at the beginning of class! You will not receive credit if you do not turn in these on the first day of class. There are NO EXCUSES. 7. When submitting your summer assignment, please complete your work in Notability and submit it into Schoology on August 9th, our first day of class.

PHYSICS BASICS, MOTION, & FORCES READING & NOTES, PROBLEMS, AND ANSWERS For the summer assignment, please download this College Physics textbook pdf from OpenStax College.

CHAPTER 1-8

MECHANICS

Read Chapters 1-8. Review concepts and equations in each chapter. Pay close attention to the author’s notes and observations. Complete IN-CLASS EXAMPLE PROBLEMS on pages 3-6 of this packet.

PHYSICS BASICS, MOTION, & VECTORS IN-CLASS EXAMPLE PROBLEMS DISPLACEMENT, VELOCITY, & ACCELERATION 1.

A car is moving in the negative direction at a velocity of -9.00 m/s. It then undergoes a positive acceleration of +0.40 m/s 2 for 10.0 seconds. What is the car’s velocity at the end of the acceleration?

2.

Two trains are traveling in the same direction on parallel tracks, where train A is moving at 50.0 km/h, and train B is moving at 60.0 km/h. If train B is initially 20.0 km behind train A, how long will it take for train A to catch up to train B?

KINEMATICS 3.

In 1865 Jules Verne proposed sending men to the Moon by firing a space capsule from a 220.0 m-long cannon, where they would have exited the cannon traveling at 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during the launch?

4.

A certain arrow is accelerated by a bowstring at a rate of 42.0 m/s 2. Assuming it starts from rest, how much time is required for the arrow to travel through the first 15.0 cm displacement during its acceleration?

FREE-FALL 5.

A ball is thrown straight upward from ground level at a speed of 15.0 m/s. How much time passes before the ball lands back at the same height from which it was thrown? (Neglect any effects of air resistance.)

6.

A model rocket is launched straight upward from rest at ground level. It accelerates with a constant upward acceleration of 2.0 m/s2 until its engines stop at an altitude of 150.0 m. Assuming no parachute opens up, and no air resistance in general, how much total time does it take for the rocket to reach its highest point?

VECTORS 7.

A toy airplane moves upward for 15.0 m at 10.0 above the horizontal, then travels 20.0 m at 14.0 below the horizontal. a. What are the x- and y- components of the plane’s first displacement?

b. What is the plane’s total displacement?

PROJECTILES 8.

A projectile is launched horizontally at 12.0 m/s from the top of a building that is 40.0 m tall. How far does the projectile move horizontally before it lands on the ground?

9.

A stone is kicked horizontally off of a 90m-tall cliff, at an initial speed of 23.0 m/s. How fast is the stone moving at the moment that it strikes the ground?

10. A bullet is fired upward from ground level with an initial velocity of 200.0 m/s at 42.0 above the horizontal. What is the highest point above ground level reached by the bullet? (Neglect any effects of air resistance.)

11. A ball is launched from a cliff at an initial angle of 35.0 to the horizontal, at a speed of 30m/s. What is its speed at the time it has moved 200.0 m in the horizontal direction?

FORCES AND APPLYING NEWTON’S LAWS IN-CLASS EXAMPLE PROBLEMS NEWTON’S 2ND LAW 1.

A 2.00 kg box is sitting at rest on the ground. A rope is tied to the box pulling it to the right, while a frictional force acts to the left, opposing the box’s motion. a)

If a 10.0 N tension force is required to pull the box at a constant velocity, calculate the frictional force acting on the box.

b) Assuming the same frictional force continues to act on the moving box, how quickly will the box accelerate if the rightward tension force is increased to a 15.0 N force?

c)

Assuming the same frictional force continues to act on the moving box, what rightward tension force will cause the box to speed up at a rate of 4.0 m/s2?

d) Assuming the same frictional force continues to act on the moving box, what rightward tension force will cause the box to slow down at a rate of 3.0 m/s2?

WEIGHT AND NORMAL FORCE 2.

A 5.00 kg rock is sitting on a scale on the floor of an elevator. a)

Assuming the elevator is at rest, find the weight of the rock, and the normal force exerted on the rock by the scale.

b) Now the elevator accelerates upward at 2.30 m/s2. Find the weight of the rock and the normal force acting on the rock.

3.

A fisherman pulls a fish vertically out of the water with an acceleration of 2.50 m/s 2, while using very light fishing line that has a breaking strength of 22.0 N. Unfortunately, the line snaps under these conditions. What do you know about the mass of the fish?

CONNECTED OBJECTS 4.

Three objects are connected as shown in the picture, and are moving across a frictionless surface. a)

If a 50.0 N horizontal force pulls the front block to the right, find the acceleration of the whole system.

b) Now find the tension in the cord connecting the front two blocks.
