Hey, so I am just working on a second year Analytical Mechanics assignment, and right now dealing with oscillations. I have two questions I am stumped on and don't know if I have it right. It is probably basic, but just checking. 6. The frequency fd of a damped oscillator is 100 Hz, and the...

Anyone? Do I need to include other attempts?

I agree with gneill, this is a very basic question. I don't understand how high school math or physics teachers can't get this, or even your parents if theyre engineers. Attempt it and I'll give you a hand if you need it.

1.5x + 0.6y = 1200(0.8) Hopefully that helps. If you don't understand where I got that from or what to do from here, let me know.

Just bored and looking for some new (<2 years ago) articles people find interesting. If anyone knows of any diseases that may be caused by neurological disorders which isn't proven yet, for example diabetes, they'd be a good start. Cheers

A particle of mass m moves without friction subject to a force F(x) = −kx + \frac{kx3}{A2}, where k and A are positive constants. It is projected from x = 0 to the positive x direction with initial velocity v0 = A\sqrt{\frac{k}{2m}}. Find: (a) the potential energy V (x), (b) the kinetic...

Any help would be greatly appreciated.

Keep as many digits throughout your work as you can, then round at the end.

So here's the question: An ant crawls on the surface of a ball of radius b in such a manner that the ants motion is given in spherical coordinates by the equations: r = b, \phi = \omegat and \vartheta = \pi / 2 [1 + \frac{1}{4} cos (4\omegat). Find the speed as a function at time t and the...

Hey thespaceman, I actually have some experience with weather balloons, so thought I'd post what I know. Give consideration that this is taken from practical experiments personally and not from literature. Your first question about ascent change with regards to altitude. It should not change...

Structures of Glycine at pH's 1, 5.97 and 13, just wondering if anyone can confirm these, been a while since molecular bio. pH 1 pH 6 pH 13 Regards, Andrew Johnson

6.60 -micro C particle moves through a region of space where an electric field of magnitude 1200 N/C points in the positive x direction and a magnetic field of magnitude 1.01T points in the positive Z direction if the net force acting on the particle is 6.23 x 10^-3 N in the positive x...

Probably a dumb question, but I have never had it explained to me. I was just wondering if someone would be able to tell me what anti-matter is, from basics, how it is formed and how it interacts with normal matter. -Johnson

Does this work only with crystal wine glasses, or does normal glass work as well?

This is the same as a centrifuge. Spins everything around and around at high speeds, heavier masses going more vertical, lower mass sinking to the bottom. This is from the centrifugal force giving off a greater force than that of gravity. I think that's right anyways.
