**GRADES ****- Check your grades and make sure they
are accurate. If not, see me ASAP! Bring papers.**

**SECOND

of problems:**

**1)
Momentum - collisions, elastic or inelastic**

**2) Angular
velocity and acceleration**

**3) Radial
force on a vehicle on a turn**

**4) Escape
velocity**

**CALCULATORS - **DO NOT forget your calculator on exam day, Friday
May 25th. Put it in your shoe or tape it to your steering wheel
the night before. I will NOT loan you one. Don't even ask.

**FINAL EXAM INFO**** - See exam schedules posted around
school. Review info below, somewhat disorganized, but it's there.**

**Rocket Exemptions**
- READ CAREFULLY! These are given to guys who finish in the top
three places in each class AND whose grades are 'B' or above.
These are the potential names. I have NOT checked the 'B' part
yet, but I wanted to get the times up. I will modify these as
needed soon. Again, these exemptions are PENDING the 'B' grade.
These times are now posted on Haiku.

**BOOKS**** - If exempt, bring your book to 104 with
your name in it. If not, bring it to the final or bring it to me
before. Make sure your name is in it.**

**Rocket Finals on Wednesday**
- **NOTE:** Only the
top **THREE** teams from each class will go on to
the finals on Wednesday, May 23.
Have your rocket ready to go! You are NOT required to be in the
finals if you don't want to be.

**Rocket Grades increase**** - Teams that finish ****first, second, or third**** in the finals** on Wednesday, May
23, will have their 2nd semester grade increased by three notchs
for first (B > A), two notches for second (B > A-), and one
notch for third (B > B+). **FIRST
PLACE - ( ) - SECOND PLACE - ( ) - Also cash prize winners but no
exemption for rocket - THIRD PLACE - ( ) - FOURTH PLACE - ( ) -
FIFTH PLACE - ( )**

**FINAL EXAM EQUATION
SHEET ****Word**** ****PDF**** -Two pages. This is NOT the
exact one you will receive on Friday. You may not use your own
sheet.**

********* Review everything down to the
bold ****blue**** line. Also, look at ****old exams****. Some problems may come from
old exams. *********

**Suggested example
problems and some worked out problems that may be helpful. These
do not cover all topics.**

**Final
Exam covers chapters 6, 7, 8, 15, 16, 17) **

**ALSO! -
Bring your ****textbook**** to the test. ALSO, bring your ****calculator****. I will not be loaning them
out. Put it in your shoe the night before. Don't step on it
Thursday.**

Problems 1 to 7,****
****quiz**

**Chapter 7
- Rotational Motion and the Law of Gravity - ****Sections 1-6**

**Ex.
Problems 1 to 9, 11-14,**** ****centripetal
acceleration ****quiz
(****Word****,**** ****PDF****), ****centripetal acceleration ****quiz (****Word****,**** ****PDF****), ****centripetal acceleration ****quiz (****Word****,**** ****PDF****), ****rotational kinematics ****quiz (****Word****,**** ****PDF****), ****Also, here are ten 2nd law
centripetal acceleration problems.**** (****Word****,**** ****PDF****)
**

**1) Mars is 2.278 x 10**^{8}**
km from the sun and takes 687 days to orbit the sun. If Neptune
is 4.494 x 10**^{9}** km
from the sun, how long is its year in days? (Use Kepler's third
law. Set two equations equal to each other and cancel what you
can. You should be left with only T and r to various powers.)**

**2) The outermost
particles in Saturn's rings are 1.35 x 10**^{5}**
km from its center and are moving at 17 km/s. Find the mass of
Saturn. (Use Newton's law of gravitation (force) and the radial
accelation to find the radial force. Set those equal and solve
for mass.)**

**3) Find the location of
the place between the Earth and the moon where the gravitational
force on an object of mass m would cancel. (Call the total
distance, 3.84 x 10**^{5}**
km D and the distance this place is from the moon x. Write the
two force equations and set them equal. Call the mass of the
earth m**_{e}** and the
mass of the moon m**_{m}**.
The mass of the earth is 5.98 x 10**^{24}**
kg and the mass of the moon is 7.36 x 10**^{22}**
kg.)**

**HW problems -**

r_{e} = 6.37 x 10^{6}
m m_{e} = 5.98 x 10^{24}
kg m_{sun} = 2 x 10^{30}
kg r_{es} = 1.49 x 10^{11} m

1.
(a) How far above the earth’s surface is the gravitational
acceleration equal to 1 m/s^{2}?

2. (a) What is the length of the year on the planet Uranus in Earth years if it is 19.182 AU from the sun? (b) If its mass is 14.5 as large as Earth's and its radius is 25 900 km, what is the surface escape velocity?

3.
The moon Nereid has a period of 359.9 days and is 5.56 x 10^{6}
km away from Neptune. How far is Triton from Neptune if its
period is 5.877 days? Do not look up the mass of Neptune.
Use Kepler's 3rd.

is NOT guaranteed to cover everything we did nor is it guaranteed
to cover every problem that might appear on the Semester Exam. - **

**Also, some of the problems/tests/worksheets are older
and may differ in style from what I taught you in class. Class
examples from THIS year are the way I want you to do the
problems.**
