Kepler Problems

1) Mars is 2.278 x 108 km from the sun and takes 687 days to orbit the sun. If Neptune is 4.494 x 109 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 105 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 105 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 me and the mass of the moon mm. The mass of the earth is 5.98 x 1024 kg and the mass of the moon is 7.36 x 1022 kg.)

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 106 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.

Monday, Nov 26 - Newton's second law test with solutions.


The TEST scheduled for Tuesday has been moved to Wednesday. A good chunk of the afternoon class will be at the NMSQT luncheon and I want everyone to take the test the same day.

Practice problems. Answers here.

Monday, Oct 29 - Newton's second law example problems. You should eventually be able to do all of these without looking at notes! First page (pdf) (Word) Second page (pdf) (Word) Third page (pdf) (Word) -- Practice! Next homework - Read Chapter 4, sections 1-5. (1) Take accurate notes, especially diagrams. (2) Go over your notes nightley. (3) Go over the examples problems and diagrams very carefully. (4) Read all problems assigned. (5) Then start working on them as soon as possible. (6) Read the following handouts. Next problems 6, 7, 8, 11, 13, 14, 15, 16, 17, 23 for now.


NEXT UP - HW - Ch.3 - problems p.75 - 22, 24, 26, 27, 28, 29, 30, 31, 35, 36, 38 - Projectile quiz with answers. Practice test. Same practice test with answers. Test next week. Projectile lab today, report due Tuesday. TEST next week.


October 3 - Ch2 Exam key


Tuesday, Oct 2 - Ch.3 - HW- probs p.74 - 9, 10, 11, 13, 14. Force table lab due Thursday. Vector addition quiz, Thursday. Know how to add 2 vectors by the component method. Practice vector quiz with answers (Word, PDF) Handout on horizontal projectile motion (Word, PDF). Handout on projectile motion at an angle (Word, PDF). Lab on flat projectile motion soon.

Lab Report Format - For the Force Table lab report, show a sample calculation for the triple vector addition problem. That's the last one on your lab sheet. If you did not do the triple, use the values shown here ( Force Table ) at the bottom of the first page. Draw a force diagram using one of the double force problems you did. DO NOT draw the triple force diagram. Since your results include both magnitude and angle, it is not easy to calculate a % error for the angle. Do the % error for the magnitude but just describe the angle error.


Friday, September 27 - If you missed Friday (especially 9th period) here is a PowerPoint of some of the class notes. Vector components (PPT)

Essay question something like: "Having read the book, what do you think of Newton as a scientist? What do you think of him as a person?"

1) A person travels by car from one city to another with different constant speeds between pairs of cities. She srives for 30.0 min at 80.0 km/h, 12.0 min at 100 km/h, and 45.0 min at 40.0 km/h, and spends 15.0 min eating lunch and buying gas. (a) Deterine the average speed for the trip. (b) Determine the distance between the initial and final cities along the route.

3) Two boats start together and race across a 60-km-wide lake and back. Boat A goes across at 60 km/h and returns at 60 km/h. Boat B goes across at 30 km/h, and its crew, realizing how far behind it is getting, returns at 90 km/h. Turnaround times are negligible, and the boat that completes the round trip first wins. (a) Which boat wins and by how much? (Or is it a tie?) (b) What is the average velocity of the winning boat?

5) A motorist drives north for 35.0 minutes at 85.0 km/h and then stops for 15.0 minutes. He then continues orth, traveling 130 km in 2.00 h. (a) What is his total displacement? (b) What is his average velocity?

7) Need book to see graph. Get book and do problem for Monday.

17) Need book to see graph. See #7.


Thursday, August 23 - Take the circle data and draw the graph by hand. Use instructions found here: Data Collection and Analysis Lab - Hand Graph.

Buy a cheapo calculator. Availabe for about $10-12. The model number is TI-30x IIS. I have a number of gently used ones for $10. No tax, no shopping. I strongly suggest you use only purchase the TI-30x IIS. It has two lines and data is entered like the TI-83, 89. Guys who got different ones last year regretted it.
