    Depression and Finding Motivation

    I have a hard time getting motivated myself. I do notice that when I start something new (new job, new classes, new book, etc.) things are easier for awhile. Is there any way you can move to another position at work? If a complete switch isn't possible, ask for different tasks. Maybe an...

    What Is the Damping Constant for Critical Damping in a Freight Car's Motion?

    the velocity of the freight car would be zero when the spring is fully compressed. so if the velocity is zero when the spring is completely compressed, then the first equation would be \frac{d^2 x}{dt^2} + 2\beta(0)+ \omega^{2}x = 0 = \frac{d^2 x}{dt^2} + \omega^{2}x = 0...

    What Is the Damping Constant for Critical Damping in a Freight Car's Motion?

    well, i know the general solution for the differential equation is x(t)= e^{-t * \beta}[A_{1}exp(\sqrt{\beta^2 - \omega^2}) + A_{2}exp(-\sqrt{\beta^2 - \omega^2}) Should I use this to find the compression of the spring?

    What Is the Damping Constant for Critical Damping in a Freight Car's Motion?

    Homework Statement I'm a little ashamed to post this, because I bet I'm missing something obvious, so try not to laugh... A freely rolling freight car weighing 10^4 kg arrives at the end of it's track with a speed of 2 m/s. At the end of he track is a snubber consisting of a firmly anchored...

    Balancing Full Time Work and Full Time School: Is it Possible?

    could you go to school part time? government aid is usually awarded to students who are at least half time enrolled. i know in my area and in my circumstances, the government aid they gave me was enough to fully pay for my community college experience, and i just went part time. i still go...

    What to do about someone who litters?

    my mil's apartment is littered with cigarettes all over. people smoke and then throw the butts over the rail to the ground. i saw a child playing in the dirt scooping up used cigarettes and other debris into his toy dump truck, and i think that's why I'm so fired up right now. i cleaned that...

    What to do about someone who litters?

    the first day of class i sat next to this guy. when he left the room (early, he seems pretty rude) he shoved his extra large sized drink cup under the chair. i decided not to say anything at the time, because maybe he's a new student and doesn't understand. but it happened again tonight. he...

    Can I Get My Bachelor's in Physics as an Adult?

    hi. I've got the family/ mortgage/ job thing going on, too. I've found that my public state university has many upper level evening math/ physics classes. if you can't take time off your work, per se, would it be possible to move around your schedule? for example, you can take a Tues/ Thurs...

    Programs Should I Pursue a Career in Physics or Consider Other Options?

    i have no idea any more. it's strange, but i don't know what my interests are or what I'm good at. i started this path because it's what i enjoyed in high school, but it's been a few years. I'm going to the career center at my school next week to see if there's anything out there for me.

    Programs Should I Pursue a Career in Physics or Consider Other Options?

    Course Description: Review of: Complex numbers, vector spaces, linear operators, and vector integral systems. Study of Fourier series; product solutions of PDEs; and special functions. Co-requisite: Differential Equations (MATH 2420 or equivalent). i think it's a bit of both.
