Serway & Jewett — Superposition and Standing Waves: Problem 15

Review. A sphere of mass \(M = 1.00 \text{ kg}\) is supported by a string that passes over a pulley at the end of a horizontal rod of length \(L = 0.300 \text{ m}\) (Fig. P17.15). The string makes an angle \(\theta = 35.0^\circ\) with the rod. The fundamental frequency of standing waves in the portion of the string above the rod is \(f = 60.0 \text{ Hz}\). Find the mass of the portion of the string above the rod.
