Really Mrs.A, So if you are really teacher, your going to give every single student in your class a zero. Now I may not be a master in a science and degree but HAVE SOME COMMON SENSE!! First of all, some of us (like me) have learning disabilities and we

Each grade answer is different and they do change the answers so they know people aren't cheating. So people need to specify what grade, what school, and the date. I like using this site for information and practice but I don't trust the answers. And if

Phy? F(t)=m*a_x(t)=-F0+(t/ts-1)*F1 =>ax(t)=-F0/m+(t/ts-1)*F1/m integrating from 0->t vx(t)-vx(0)=-F0/m*t+(t^2/(2*ts)-t)*F1/m you get Vo from here by putting t=0. Now, Vx(t)=Vx(0)-F0/m*t+(t^2/(2*ts)-t)*F1/m Integrating between 0->t We get

KS. The mod(x_2-x_1) is actually really simple. All you need to do is this... 1/2*k*(x_1)^2=(mu_k)*m*g*d solve for d.... your d value will come equal to your x1...the magnitude I mean. This means the body starts moving and comes to rest at x_0=0 itself. :D

And guys, those of you who're not interested in the math portions. Let's be honest, Lewin's lectures are the important bit for you. It's difficult to maintain the honour code and get certs if you're not happy with math. I think, just watching Lewin's

Phy... your k is 40... F0 is obviously 0. I wasn't telling you because I thought it'd help you learn how to use wolfram better. Alas... Somebody help me with the Mass Spring sum? Everything else i've finished off :)

now type in F(x) in wolfram alpha... you'll get 3 roots... 1)x=0 and 2 more equal roots with opposite signs. the positive root must be chosen. Now in wolfram alpha type in Talyor Expansion( and type in your F(x)) at x=the positive root. the second term's

I'l give you the answers... but ask yourself, are you learning anything at all if you just fish for answers from strangers? Most of us come here if we get stuck!! F0=0,k=80...do try to find out T on your own?

31. ## Physics

no. Your equations are all messed up. U(x)=λ/4*(x2−a2)2+(b/2*x2) =>U'(x)=F(x)=λ/4*(4*x^3-4*a^2*x)-b*x Now using your lambda,a,b values: U'(x)=3x^3-40x hence: your roots are 0, 3.651483717, -3.651483717

ss01 look.... its quite simple.... F0... comes to 0 for mine... and to get k, do the following: Since I don't know the values of a,b,lambda you have... F(x)=dU(x)/dx now type in F(x) in wolfram alpha... you'll get 3 roots... 1)x=0 and 2 more equal roots
