Calculus #105

The requests for these assignments are more frequent now; this is a very good thing. I'll be posting the next several in a couple of days since I'll be away from the computer for awhile. Do check in though.

Calculus #104

OK...here it is #104. We've got quite a bit of work to do so leave a comment when you get the assignment and I'll know when to post the next one.

Uniform Circular Motion

Read the links (the Physics Classroom link is a good one) and give #15-19 a try in the back.

String and Pulley Problems

The next installment for our studies of Newton is here. I will recommend completing questions numbered 11-13. They can be a little time consuming but well worth the effort. Algebraicially this topic is little intimidating so come and see me about the math. My main concern initially will be about setting up the free body diagrams and the net force statements; once you have mastered that the algebra will "happen naturally".

Physics 30-Vector Addition

Whew...that's chapter 5 all done with, sort of. Chapter six will require you to remember everything so far, and we'll build on it some. Follow the links for the first installation of your notes on Chapter Six-VECTORS!

Calculus #103

Calculus...we're ready to go. As you know I have been having some difficulty with posting assignments due to some graphics glitches, and now I believe I have fixed them (really just found a way around them with the help of some of your classmates-Thanks W35, Hair, Essential...)

I have numbered the assignments by unit, topic, objective. Be sure to use this notation when you post questions. Hopefully you're ready for your third assignment now. Answers for your assignments can be checked with me (I'm considering posting them too), and we'll need to set a quiz complete date before long. Check the link at the side and print off your assignment then comment to let me know you've got it printed off alright. I'll be constructing a timeline to give us some idea of what needs to get done by when.

Happy math....

  2. 750 kg
  3. 75 N
  4. 60 kg
  5. 3.3 m/s^2
  6. a) 3.6 m/s^2, b) 4.9x10^2 N
  7. 1.6x10^-26
  8. a) 2.0 N, b) 0.02
  9. 7.4 N
  10. 0.60 m/s^2
  11. 3.3x10^3 N

  13. 3.3 m/s^2

Good luck.

Calculus Assignments...Well almost

OK...it's getting late and I need to get some other things done yet so I'm afraid I'm going to have to give up for tonight. However, I did manage to store some stuff on the server and I have the Calculus #1 link working...just not well yet. I stored the assignment as a jpeg, but for some reason I only got the first page and it doesn't look printable. I suppose though these things take short steps at first. If you have some advice feel free to comment (or help...you know where to find me).

Calculus Assignments

Hello there Calculus students.

I had originally hoped to post your assignments and things on here, but it's looking like the best solution is to e-mail them to you directly. If this is the best option for you and I can't find a way to post them here or somewhere else in the vast real estate of cyber-land let me know by a comment to this post and I'll send along Calc#2.

Welcome

Welcome to the new blogspot.

This is as much of an experiment in communication as anything I've done so I'll need your help and expertise to make it everything we'd like it to be.

To start off then we need a discription for the blog (maybe even suggestions for a new title, but I'll need to deal with one thing at a time untill I get good at this). Before you start submitting suggestions for a discription of our blog consider a few things first.

We are writing for a global audience. Don't let this intimidate you, but keep in mind that you want to put your best foot forward.

Ideally this will be a place for all of my students to contribute things that are related to the subjects they study with me, to learn from others, and to submit things of interest to math or science.

Hope to see your suggestions soon....blog-on.
Mr.A
