Homework Statement Two coins, one at rest (c1), the other flicked towards the other (c2). Initial positions are marked, as are final positions and angles. Coordinate system's origin is placed at center of C1 with +x in direction of C2's motion. knowns: \mu = .36 V1 = 0 C1 final position- 10.25...

thanks i just checked in the answer book and that is the answer thanks a lot!

ok so here's how i went about this: Ffr \leq uk x Fn Fn = mg Fn = 9.8m Ffr \leq .80 x 9.8m m is of no regard in this problem therefore Ffr \leq 7.84 m/s2

could someone please clarify this? I am studying this on my own (no teacher) and we haven't really gone over rolling i have the exact same problem but have no idea how to start Thanks.

awesome! thanks for the help i bought a few sensors off a surplus store that look similar... thanks!

What's the range on one of those things? I'm looking into something with about 2-3 ft sensitivity

lol not all in one year i would hang myself if i did that hahahaha my plan goes like this (Just math and science): Freshman- bio I, Alg. II H Freshman Summer- Chem I, Precalc, Physics I Sophomore- AP Physics, Geometry H Sophomore Summer- Calc AB (or equivalent at local college) Junior- Calc BC...

do you think taking a biotech or bioengineering major is worth it as it will similarly allow me to remain diverse? yes i am a straight A student and i am taking many advanced courses. I plan to take AP Physics, AP Bio, AP Chem, Calc AB and BC, and possibly AP Statistics... do you think that sort...

alright so here is the basic premise of the task: http://www.youtube.com/watch?v=6tl9aMkzitQ&eurl=http%3A%2F%2Fwww.ecsel.psu.edu%2Fusers%2Favanzato%2Frobots%2Fcontests%2Ffirefighting%2Findex.htm&feature=player_embedded im planning to use an arduino control board with a motor controller and...

would have voted indian but i am indian so technically not ethnic for me but voted mexican as you can't beat it!

by couple do you mean like 2 or 3 sensors to detect the light??

no cars- a rail commuter system to take us from our house to where we wish... personal robots that will perform tasks for the benefit of human society within the next 50 years- obesity rates at near 60% due to there being no need for personal locomotion after the next 50 years- # of obese people...

yeah that seems like it'll probably be what it comes down too... my current worry is that if i don't focus on one or the other, i won't be able to get into a good school for engineering or medicine. I also didnt want to pick engineering if there would be a saturation of jobs in the market, i.e...

i am looking into participating in a local firefighting robot competition and i have many of the parts necessary, one thing i have yet to decide on is my method of finding the candle which is placed in a random room. Originally i had intended to use an infrared sensor with a filter, but i was...

my dad is a software engineer at IBM and I've been to work with him and programmed a lot of stuff... i love programming too lol I've also been to work with an uncle of mine who is an anesthesiologist and i love his work too... i really like engineering, especially the computer sciences and...
