1. The problem statement, all variables and given/known data a 50m length of string with mass 0.0175 kg has waves traveling at 112 m/s. There is a mass attached to the string, 0.45 kg that is creating a 4.41 N tension. What is the frequency of the string vibrator? 2. Relevant equations v=f*λ f= [√T/(m/L)]/2L 3. The attempt at a solution I can't for the life of me get to the right answer, i know that it is 187 Hz, but I'm just not doing the math right or something like that.
