thank you guys. you are right. this equation is wrong;
\stackrel{\rightarrow}{F}_{x} = m\ddot{r} = -4/3 G \rho \pi m \sqrt{r^{2}-h^{2}}
It should be
\stackrel{\rightarrow}{F}_{x} = m\ddot{r_{x}} = -4/3 G \rho \pi m...
Its a central forces problem where the mass can only move in the x direction along y = h resulting in Simple Harmonic Motion. (h is a constant)
F = -4/3 G \rho \pi m r
F_{x} = F Cos \theta = F\sqrt{r^{2}-h^{2}}/r
F_{x} = -4/3 G \rho \pi m \sqrt{r^{2}-h^{2}}
\rho = M/V = Constant
F_{x} =...
Hello
I'm trying to find a formula for a Simple Harmonic Oscillator.
After some algebra I've got it down to;
\ddot{r}-A*\sqrt{r^{2}-B^{2} } = 0
where A and B are constants.
I'm trying to get it down to be in the form of
\ddot{r} + C*r = 0
I am feeling like a dummy cause it...
<---- feels kinda dumb
Thanks for your replies doc. I did have the wrong reference tables. I would not have noticed until now.
here is the correct link

you are awsome :)
wow that was fast. thanks for your reply.
If that is the case, then I did overlook that. However I looked at the reference sheet again and I don't see it. this is the link for the pdf

do you have something different?
hi I am new here, but I signed up to ask this question. I was looking at a high school physics exam from last june and one of the questions seems to me like it's unfair. I think they didn't give enough information to solve the problem. here it is;
