Halliday, Resnick & Walker — Force and Motion–I: Problem 72

Block and three cords. In Fig. 5.43, a block B of mass \( M = 15.0 \text{ kg} \) hangs by a cord from a knot K of mass \( m_K \), which hangs from a ceiling by means of two cords. The cords have negligible mass, and the magnitude of the gravitational force on the knot is negligible compared to the gravitational force on the block. The angles are \( \theta_1 = 28^\circ \) and \( \theta_2 = 47^\circ \). What is the tension in (a) cord 3, (b) cord 1, and (c) cord 2?
