1. The problem statement, all variables and given/known data A cord with a mass of 40g is tied between two supports with a tension of 19.2N. The natural frequency of the cord is 10Hz. Find the length of the cord a.1.2m b.2m c.289m d.34cm Using your answer from Question 3, how long does the wave take to travel from one end of the string to the other? a.0.1s b.0.05s c.50s d.20s 2. Relevant equations v=squrt(forcetension/(mass/length)) v=wavelength/Period=wavelength*frequency 3. The attempt at a solution Knowns: fixed ends, string. mass = 0.040 kg Force Tension = 19.2N Natural Frequency = 10Hz length of the cord = ? Calculated: Period = 0.1 s Weight = 0.392 N Other stuff: Velocity = ? Wavelength = 2L = ? I've basically just stared at it and played around with everything I can think of which gets me no where close to an answer, for the past hour trying to figure out what to do, Made an account just to ask this forum about it.
