On an ideally elastic and homogeneus string, the square of the speed is the tension upon wich the string is subjected, divided by its linear mass density (mass per unit lenght). That is v^2 = T / (M/L), where v is the wave speed, T the tension, M the string's mass and L its length, so M/L comes to be the linear mass density (for an homogeneous string).

A cello string 75m long has a 220-Hz fundamental frequency How do you find the wave speed along the vibrating string?
75 x 2 = 150 cm [wavelength = 2x part of string that it's vibrating] 150cm / 100 = 1.5m [convert to meters] 220s x 1.5m = 330m/s [speed] So in a way, your measuring is wrong due to the fact that you measured the whole string instead of the part that's vibrating after being plucked or bowed.
What is the formula in getting the maximum speed?
A point on a violin string is vibrating transversely at 500 cycles with an amplitude of 1mm. Find the maximum speed and acceleration of this point.
What are the laws of vibrating strings?
Avibration in a string is a wave. Usually a vibrating string produces a sound whose frequency in most cases is constant. Therefore, since frequency characterizes the pitch, the sound produced is a constant note. Vibrating strings are the basis of any string instrument like guitar, cello, or piano. The speed of propagation of a wave in a string is proportional to the square root of the tension of the string and inversely proportional to the square root of the linear mass of the string.

Is a string vibrating at the fundamental frequency the length of half the wavelength?
This question can't be answered as asked. A string vibrating at its fundamental frequency has nothing to do with the speed of the produced sound through air, or any other medium. Different mediums transmit sound at different speeds. The formula for wavelength is L = S/F, were L is the wavelength, S is the speed through the medium and F is the frequency. Therefore, the wavelength depends on the speed of sound through the medium and directly proportional to the speed and inversely proportional to the frequency.
How do you calculate forse on a speed time graph?
If you only have the speed/time graph, you can't calculate force out of it. You could if you also knew the mass of the object that's speeding along, but not with the speed alone.

There is 260g block on a 50cm -long string swings in a circle on a horizontal frictionless table at 50rpm What is the speed of the blockWhat is the tension in the string?
The linear speed will be: v = 2 * pi * r * f, where r is circle radius, f is rotations per second. To calculate tension, we can use formula for centripetal force, which is: F = mv2 / r. This centripetal force will be the tension in the string.
If the tension in the string is doubled what will be the effect on the speed of standing waves in the string?
The speed of the standing waves in a string will increase by about 1.414 (the square root of 2 to be more precise) if the tension on the string is doubled. The speed of propagation of the wave in the string is equal to the square root of the tension of the string divided by the linear mass of the string. That's the tension of the string divided by the linear mass of the string, and then the square root of that. If tension doubles, then the tension of the string divided by the linear mass of the string will double. The speed of the waves in the newly tensioned string will be the square root of twice what the tension divided by the linear mass was before. This will mean that the square root of two will be the amount the speed of the wave through the string increases compared to what it was. The square root of two is about 1.414 or so.
How much centripetal force is needed to keep a 0.24 kg ball on a 1.72 m string moving in a circular path with a speed of 3.0 ms?
Calculate the centripetal acceleration, using the formula:acceleration = speed squared / radius Once you have this acceleration, you can use Newton's Second Law to calculate the force.
How is the higher note produced on a single string of a stringed instrument?
A higher pitch or note is produced by either shortening the string length by fingering (as in a guitar or violin), or by tightening the string, as in tuning a guitar. Higher pitches can also be played by lightly touching a string at its exact midpoint while plucking it, which suppress is fundamental pitch will allowing its harmonic to sound. This would produce a sound one octave higher.
