Hi troutkibe, you're reasoning seems sound. Your equations seem sound too (although the bracketing is a little funny in part "The Attempt at a Solution "[/B], but I'm guessing that's a typo?). Maybe give us the numbers you need to plug in and we can try plugging them in too (might just be the...

Look at Fresh_42's comment, he/she has corrected my edit. EDIT: You can see it in the plot btw, what Fresh_42 is saying :). Good luck.

Hi Chetzread, You may be a little confused because typically we see the equation y = f(x). My advice is to reword the equation to z = f(x + y) = f(u), where u = x + y So ask yourself what is the domain of f(u)? What values can u take? What values of x and y add to give u? You are correct, both...

Hi FallenApple, I'm not too experienced with this, but can offer a little advice (maybe). (1) Have you had a look at statistical mechanics? The field attempts to understand bulk properties from microscopic interactions using statistical methods (2) Statistical mechanics can be applied directly...

Thanks :)

Hi Josiah, perhaps a diagram would make things easier to visualize: I am not sure if cosα is required for the formula: Fƒ = μmg⋅cosα My physics textbook "Physics for scientists and engineers with modern physics" by Serway/Jewett states that the friction force is obtained using the equations...

I'm not sure I follow the third line: f’(x)=((k(x−3)^2 (x))/3)+C Maybe try expanding (x-3)(x-1) before integrating. Also you want a quartic (order 4) so does that mean your answer can be found with the first derivative? Or do you need to do an extra step? EDIT: I mean the 4th line not the...

Hi Jaimee, have you tried integrating the second derivative? Or are you unsure how to do the integration?

Hi everyone, I've recently completed my undergraduate studies, and I'm now looking for my next step. Hopefully I can find something interesting and inspiring in these forums that might help me in shaping my future goals.
