There is a glitch in the matrix.

That's what I got.
I'm actually learning this same exact shit as a 3rd year in college right now //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

I ain't mad at ya...I took this Physics three semesters ago (technically 2 if you exclude the summer semester I took to turn my F in Differential Equations to an A). I'm on my 2 second year in college too. Something still doesn't seem right though about my answer...I forgot how to check it...the main thing you need to remember!

I already know the 178.52 should be 178.752 => turns the answer into 245 something.

I did the problem without looking at your work and got the same answer, so I'm guessing it's right unless we both fuked up somewhere.

Hooray for AP Physics (thats what I'm taking this year too) Yeah Lemans, for that problem all you need really is trig once you find the normal force/ friction force

yeah man i know, sumone got it right (250N). but i ****ed up the EFx part REAL bad, and i can't figure it out. my cousin (computer engineer) did it in like 3 seconds

but didn't explain it..

im learning that and im in 8th grade lol

they teach laws of sines and cosines, tangents, vectors and other ap physics in grade school now? either you are extremely bright, but more likely than not u are just confused.

We actually were required to take physics, with those types of problems, my freshman year in high school....trig is taught fairly early now (thought I did go to a special math and science school half the day, so I wouldn't assume that was typical of high schools).
