World's largest guitar - frequency of vibration

AI Thread Summary
The discussion revolves around a physics problem involving the world's largest guitar, specifically calculating the frequency of vibration based on the string's length and wave speed. The fundamental wavelength is stated to be twice the string's length, and the wave speed is given as 9.0 x 10² m/s. A participant questions the origin of the frequency value of 50.0 Hz, which is not provided in the problem statement. The correct relationship between wave speed, frequency, and wavelength is confirmed as the equation speed = wavelength x frequency. The conversation emphasizes the importance of starting new threads for distinct questions to maintain clarity.

I have a problem on my sheet that is confusing me. The problem states The world's largest guitar, which was built by high school students in Indiana, has strings that are 9.0 long. The fundamental vibration that can be induced on each string has a wavelength equal to twice the string's length. If the wave speed in a string is 9.0 x 10 squared m/s what is the frequency of vibration?

The given is f=50.0 Hz L= 9.0 m

My question is where did they get 50.0 Hz when it's not stated in the problem. Or am I reading the problem wrong.

You are given the wavelength and the wave speed. You must calculate the frequency. What relationship ties wave speed to frequency and wavelength?

(I split this off into its own thread.)
 
um is it the equation speed= wavelength x frequency
 
Exactly. That's all there is to it.

Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
