Ok, so this is what I currently have for U:
If I solve Newtons law of gravitation for M I get M=\frac {Fr^2}{Gm}. I then substitute this value for M in the equation Work=GMm(\frac{1}{r_{2}}-\frac{1}{r_{1}}) I get Work=F(r_{2}-r_{1})
Is this a valid equation for work in the situation...
This is a problem that has been giving me trouble, wondering if I could get some input:
A space probe of mass m is dropped into a previously unexplored
spherical cloud of gas and dust, and accelerates toward
the center of the cloud under the influence of the cloud’s gravity.
Measurements...
Once more into the breach
Ok so at least I know I was on the right track. Thanks both of you guys for responding so quickly after my 2nd post, yes your right L should be the radius, and good call Gokul43201 on the T=sqrt(M/k).
If I could trouble you for a little more of your time...
Clarification
Sorry I tried to quickly summerize the problem, but I guess i didn't make it very clear. Her is a link to the problem online.

Now unless I'm mistaked the wording seems to suggest that the relevant forces are all acting on...
Maybe I'm just losing it but I can't seem to find a way to reduce this equation to the terms it requires:
A weight is suspended on the end of spring that is stiff enough to have no perceptible sag or bend and a equilibrium length of b. If the system is undergoing steady circular motion in...
Sorry to be so long in responding, I got a nasty flu bug. The above information was just what I needed to break through my mental block, thanks for your prompt and informative response.
Clarification
Sorry, I should have specified more, the problem that I'm having is with the resolving of the actual equation. Since the block has not passed through the wall the horizontal force is being countered by the normal force, causing balance in the x axis. What I believe I'm looking...
Ok, I've been having some real trouble with this problem. Either I’m missing some key piece of reasoning or it’s harder then it seems.
”If a block of mass m is pressed against a vertical surface by a constant force Fh, what are the maximum and minimum angels that that force can be applied...
Thanks Everyone
Thank you everyone for the assistance, It was definatly the aright=2aleft factor that I was missing, I also ended up having to review more basic Atwood machine problems before I fully grasped it. Thanks again that one was driving me crazy.
I was working my way through a series of problems when I came up against one that has me stuck. If anyone here can assist I would certainly appreaciate it. I found a exact copy of the problem online here: http://www.faqs.org/docs/Newtonian/Newtonian_145.htm
