Hey,
Just need to evaluate this limit, I know that the answer is 0, but I can't figure out how to prove it. Any help is greatly appreciated.
lim(x-0) of (sin(cosx-1))/x
Thanks.
I've solved it now... I was supposed to assume that since resonance was occurring, the natural frequency was approximately equal to the frequency of the driving force.
I can see what you mean (I think :smile: ). If I knew \omega_n I would be able to solve the problem. However, I'm not sure how I should go about finding \omega_n. In the physics course that I'm taking we are not really expected to be able to solve differential equations.
Thanks!
Sorry that I had to use an image file, I was having a lot of trouble using the Latex system.

Ok... We know the amplitude of the oscillations, and the force per person, so all we need to do is find Fmax, by finding other values and substituting...
Hi, I'm having a few problems with an assignment. Here is the question, and the progress that I've made so far. (If you can call it progress... )
Q) A 500g cylinder of base area a=20cm^2 and height h=30cm is floating upright in water. A 50g mass resting on top of the cylinder is suddenly...
Oh... OK, I get it now. Thanks lightgrav. I didn't realize that that was one of the properties of an ideal gas... Maybe I shouldn't be doing University Chem without having done High School Chem first... :rolleyes:
Hi, this is the question I'm having trouble with:
A gas mixture is known to contain equal numbers of moles of two gases. The mixture has a density of 1.47g/L at 1.00 atm and 298K. In a diffusion experiment, one of the gases was found to diffuse 1.25 times faster than the other under the...
Yes, telco, I thought that too, when I was working through it in my head. But when I tried to do it on paper, I couldn't simplify the other unknowns in terms of the initial velocity. I still can't figure out how to do it.
Well, theoretically there are 3 unknowns - the initial speed of object 1, the final speed of object 2, and the mass of object 2. However, since we are given a ratio of the initial and final velocities of object 1, I think I should be able to cancel these out somehow. I just can't figure out...
I was looking through the revision section of my textbook in preperation for my test tomorrow, when I came across an interesting problem, which I can't manage to solve. :mad:
The problem is:
A body of mass 2kg collides elastically with another body that is stationary. The moving mass...
Sirus, I realize that if you are in a perfectly circular orbit, then the further away from the central body you are, the slower your velocity must be to stay in that orbit. But thinking logically, if you are in a circular orbit, and the satellite (for some reason) loses velocity, surely you...
