Question: Tension is maintained in a string as in Figure P13.49. The observed wave speed is 16 m/s when the suspended mass is 3.0 kg.

Tension is maintained in a string as in Figure P13.49. The observed wave speed is 16 m/s when the suspended mass is 3.0 kg. 3.0 kg Figure P13.49 (a) What is the mass per unit length of the string? 4.5 x Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. kg/m (b) What is the wave speed when the suspended mass is 1.6 kg? 28 Your response differs from the correct answer by more than 100%. m/s
