you win!

 

Can you describe what an ocillator does? What do you mean by displaced?

 

 

isnt it winter break!>!?! wtf are u doing problems for then! just go drive you g and $@#% bit ches!

 

the answer is

(d) none of the above

=)

 

i got a 4, but that was 10 years ago.

good luck man. you'l never use that stuff again in your life.

 

my astronomy professor has taken 4 years of advanced quantum... he showed me some "simple" concepts... man, he sure made me feel dumb lol... hes only 38 too

 

i took physics back in high school... that **** was rediculous and worthless unless u wanna do that for a job. each problem took like 15 minutes and a page worth of work to figure out.

 

114.5 cm/s

anyone match? i just did it on a piece of scratch paper....didn't double check....procedure goes...

total energy = total energy, assuming no losses

KE1+PE1 = KE2+PE2 from conservation of energy

you know KE1 and KE2 from 0.5*m*v^2

you know PE1 and PE2 from k*displacement

solve for k, spring constant

plug back in to either side of the equation to find total energy

maximum velocity occurs when displacement is zero so...

total energy = 0.5*m*(v_max)^2

solve for v_max

 

oh yeah...hi! i drove a 1987 corolla fx to high school...

i'm trying to decide between a 2007 g35 sedan, 2007 350z, or 2007 328i coupe...argh!

 

There are MANY types of scillators, and I am mainly familiar with the electronic ones that produce a certain wave, like a sine wave, square wave, pulses, etc. I think he is referring to a mechanical oscillator where he spins an object at a certain speed. There is a force (motor?) that spins the object, when the object is off-center it will wobble, therefore creating an scillation. The more off-center the greater and slower the oscillation. If the object is spun at its center of gravity it will achieve max speed with zero oscillation, like a balanced tire. All these assumptions are vald if the same motor is used with the same force.

By displacement he means the distance of the axis from the center of gravity.

I am sure I could explain the electronic oscillators better, but that is not what it was in question. I hope this helps.

I am sure most of you have oscillators at home. When your cell phone vibrates that is because of an oscillator, that is a good oscillator. When your tires are unbalanced and give your car the shakes, that is a bad oscillator.

Someone please correct me if I am wrong, I studied this stuff a long time ago.

 

why isnt this thread moved

 

why is there a high school physics problem on these boards? LAMEZZZZZZZZZ. this is a fairly simple problem. Look in your book, there are a couple formulas to use.

 

Yeah, Quantum totally kicked my @ss in college. I blame it on the book and professor. I'm pretty good with numbers, but quantum doesn't involve numbers, just tons of Greek alphabet!

Its a subject where you either got it or you don't. I have a few friends who are into it and it sounds like you can do some crazy stuff with it, but learning it was a pain for me.

 

Honestly there is no way i could do this problem with out the book. Last time i took physics was 5 yrs ago soph yr of college. Crazy part is i never needed it since i decided to switch majors and deal with computers.

To each there own. Unless you go into physics field you will forget this info unless you have a reason to do it daily. You will be able to read a problem, know you know it, but won't be able to do it with out some research
