    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

    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?

    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
