Haha, yes. I am confused at what point the dr/dt is entering into the equation. If I had to guess, it comes from the 'r' term that we plugged in. (S-c1t)
However, since this is only in terms of 't' and the other values are all constants, I didn't think chain rule would apply.
Would you...
Angular momentum is conserved.
L0=Lt
L0=r x p = rm(rw)
L0=S2m*w0
Lt= (S-c1t2)(m)(V)
Vθ = r*dθ/dt
Vθ = (S-c1t2)(w)
S2m*w0=(S-c1t2)(m)((S-c1t2)(w))
S2w0=(S-c1t2)((S-c1t2)(w))
w = S2w0 / (S-c1t2)2α=dw/dt
α= S2w0 * d/dt[ 1 / (S-c1t2)2 ]
α= -2*S2w0 / (S-c1t2)3
This would be the answer if it were...
No, it isn't a constant. However, if I am understanding the problem, α is what I am trying to solve for. And if that is correct, I am confused as to what I can set the components of force equal to, so that I can solve for alpha.
I also believe I had a mistake in my Fθ component. Where I...
I only listed the torques because it was part of the question. I don't think they are of any real significance.
I guess that is wrong. Would I plug in (w0 + αt) instead?
Homework Statement
A block of mass M is on a frictionless table that has a hole a distance S from the block. The block is attached to a massless string that goes through the hole. A force F is applied to the string and the block is given an angular velocity w0 , with the hole as the origin, so...
