    Calculating the final velocity of a compressed-air launched projectile

    After reading ahead, it appears that my model is a little bit too simplistic. Upon reading about the pressure being directly related to the sum of the force provided by the collision of air-molecules against the sealing membrane, I remembered that an air-launched cannon has a "top speed" since...

    Calculating the final velocity of a compressed-air launched projectile

    Yes, interesting, though most of the content appears to be devoted to addressing oversights that I haven't over-sighted. There are some fairly similar functions, however, that might be useful in relating. Thank you.

    A question about Simple Harmoic Motion

    ooooooo... let's see... The constant in this sin function is 2*pi/3 right? Since a regular sin function has a period of 2 pi and a constant K multiplier reduces the period to 2pi/K, and K in your situation is 2*pi/3... then...

    Calculating the final velocity of a compressed-air launched projectile

    Ehhhhh... this really isn't a "homework" problem but something derived out of curiosity(But I guess it could be considered homework-esque). Homework Statement Basically, not accounting for drag or friction, what'd be the final velocity of a projectile launched from a compressed air chamber of...

    Solving a first-order nonlinear differential equation.

    Really? So w(t) = tanh(egt)? Then ev(t) = tanh(egt) v(t) = tanh(egt)/e When I tried solving it by pre-converting w in terms of v before integrating, I ended up v(t) = tanh(e^2gt)/e. I'm thinking that I superfluously inserted an e somewhere, but I don't know where. if w = ev...

    Solving a first-order nonlinear differential equation.

    Implicit differentiation about 3 years ago in Highschool is about the closest(That I know of). I didn't actually do "Calculus 2"(Differential equations included, looking at the book) but I did complete a system of differential equations sometime ago in a Calculus 3 test. But I think that was...

    Solving a first-order nonlinear differential equation.

    So I see how this might solve a problem that I *think* I was having earlier. So, e-epsilon dw/(1-w^2) = eg dt Then the left side would be integrated in respect to initial and final "w", which then could be converted into v terms post-integration(or would be it better to do it...

    Solving a first-order nonlinear differential equation.

    Took quite some time to mentally process(This format is extremely unfamiliar) and sure. I'm not really sure where you go from here(My experience with differential equations is practically nothing, beyond several glimpses on wikipedia.) but I guess I can shoot off into several random directions...

    Solving a first-order nonlinear differential equation.

    [Differential equation at the end; All the intermediary stuff is the problem behind it.] I was curious about finding the velocity function for a free-falling object using solely Newton's equations. Using the force diagram, I've deduced that m-mass g-gravitational constant f_net - net...

    Medical Dealing with Repetitive Thoughts: Understanding and Coping with OCD

    Vagueness in language? No problem - Just pick up the trade of neology, and just start creating words for those ideas you're trying to bring under precise focus.

    Medical Is the IQ Gap Between Races Genetic, Environmental, or Both?

    I believe the studies regarding Asian's IQ is that the Fluid intelligence derived IQ(Synonymously, nonverbal IQ) is only 9 points above the White's average, which is less then 1 SD. A difference of that size wouldn't be observationally noticeable in daily interaction, however it might become...

    Medical Biological limits to a Human's G - What's the limit?

    Hello. I've always wondered about the limit to Human's ability to think complexly, and what would be incorporated in that ability to think in such complicated terms. The general measurement used to quantify this is usually the IQ test, which is a measurement that depends solely on one's relative...
