Hello all,
I've just gotten back from San Diego and the ISTE (International Society for Technology in Education) conference. I haven't heard from the school yet about the book. I hope to know something on Monday. You are able to do everything on the summer assignment without the book except outline the first chapters of the book. Please check back after July 1 to see if you need to buy the book.
My apologies for the delay getting you the information. Stay cool!

Objective: SWBAT review for the AP test/final
Warm Up: Pick up one packet.
A heat engine has an efficiency of 25% and extracts 120 J of heat from a hot reservoir per cycle. a) How much net work does it perform in each cycle? b) How much heat does it exhaust in each cycle?

Objective: SWBAT understand the relationship between density, volume, mass and the buoyant force.
Warm Up: An aluminum object has a mass of 27.0 kg and a de4nsity of 2.70 x 10^3 kg/cubic m. The object is attached to a string and immersed in a tank of water. Determine the a) volume of the object and b) the tension in the string when it is completely immersed.

All students should report to the Media Center.
Bring some paper, a pencil, an equation sheet and a calculator.
Log on to this blog. Go to http://apphysicsb.homestead.com/review.html .
Choose a subject within Newtonian Mechanics and click on it. In the window pane on the left (in black) choose "Practice Questions". Complete the quiz and email me the results (heyesd@calvertnet.k12.md.us).
Choose another subject within Newtonian Mechanics and repeat the process. If time permits, take a third quiz (which will count as extra credit towards this assignment).
YOU MUST WORK INDIVIDUALLY.

Objective: SWBAT determine how well they performed on the FRQ section of an AP Physics B Exam.
Warm Up: Get out your 2009 AP FRQ's.
A 2.0 kg wooden block is on a level board and held against a spring for force constant 100 N/m which has been compresses 0.10 m. The block is released and propelled horizontally across the board. The coefficient of friction between the block and the board is 0.20. Determine the velocity of the block just as it leaves the spring. Also, determine the distance the block travels after it leaves the spring.

Objective: SWBAT relate work and energy within a problem (finish forces review- start W, P, E review).
Warm Up: A 50 kg rider on the "Rotor Ride" stands along a vertical wall in a circular room of radius 3.0 m. The room begins to rotate and at a certain point the floor drops down several meters, leaving the rider pressed against the wall. If the coefficient of static friction between the rider and the wall is 0.40, determine the minimum a) speed and b) frequency of rotation required to prevent the rider from slipping down the wall. ( Hint: draw a free body diagram of this situation!)

Objective: SWBAT review kinematic problems for the AP exam.
Warm Up: From the top of a cliff overlooking a lake, a person throws two stones. The stones have identical initial speeds. However, stone 1 is thrown downward at an angle (theta) that is below the horizontal and stone 2 is thrown at the same angle above the horizontal.
1) Draw a sketch of this situation
2) Neglecting air resistance, decide which stone, if any, strikes the water with a greater final velocity.
