an unstretched spring has a length of 0.30 m. when the spring is stretched to a total length of 0.60 m, it supports traveling waves moving at 4.5 m/s. how fast will waves travel on this spring if it is stretched to 0.90 m? (hint: for the speed of wave, use the equation of the speed of a wave on a string.)
