Old Silverback is my favorite player!

Which is certainly closely enough given various rounding / sig figs. You got it right.

There are several explanations I think. I would probably use the kinematic equations (v0, v, delta_x, a, t), and use those to solve the problem. If you're getting stuck, can you post what you've done so far, and that will give me better information to assist you?

Hi cjt100. So we can better assist, can you tell us what you've tried so far, and where you're getting stuck?

Cool video edits!!!

Sure would be nice if your teacher put something together to help with LaTeX and getting started... maybe something like a guide and even starting templates. Perhaps even a video guide? http://www.aplusphysics.com/about/LaTeX.html

This is a very common type of question, and the process of breaking up forces on a FBD into components and applying Newton's 2nd Law carries throughout the entire course. One of those things you've gotta learn. The "shortcut" that you learned isn't really a shortcut, and isn't something I'd recommend, as it won't carry through to other situations in which the third force isn't caused by gravity on a mass. I'd focus on learning how to draw free body diagrams, break forces at angles into components, and applying Newton's 2nd Law. It's the backbone of mechanics, and very important in further units as well. Good luck!

That was a pretty cool read... I had no idea about all the different split configurations. Well done!

On the bright side, replacing circuit breakers is fairly straightforward. Car engines, now... that's another story. Good luck!

@HegelBot153 Huh???

That's a lot of doom and gloom for someone who had a fantastic score on the exam...

You can do it! And as I recall, you didn't "fail" the test so much as receive a score you're not overly thrilled with. Which happens to EVERYONE in here. Keep doing what you're supposed to and it'll all work out.

Absolutely fantastic post, and I love the jumper from Stanley -- that's how you serve aggressive!

Sitting on the third base line can be pretty scary in a big-league game. Especially if you have kids to wrangle who are more interested in their popcorn than the game.

Dear Mr. Vank -- it's fantastic that you landed on the moon... but did you land on time?

Sounds like you're right back in the thick of it... how's school treating you?

Sounds like solid advice to me!

Nice job thinking about how to learn efficiently and effectively!

Nice reflection!

Thanks etracey99! Also hoping you have a great year in APC.

Nice reflections on the video... and the small print disclaimer was cute.

oh my... i'm not quite sure where to begin.

Thrilled to have you in class this year... the flipped classroom (and very independent classroom) environment takes some getting used to, but I'm sure hoping you love it by the time we're done!

Did any of these strongly resonate with you?
