Halliday, Resnick & Walker — Force and Motion-I: Problem 53

53 As shown in Fig. 5-38, body C (2.9 kg) and body D (1.9 kg) are suspended from a rigid support by inextensible wires B and A, each of length 1.0 m. Wire B has negligible mass; wire A has a uniform density of 0.20 kg/m. The whole system undergoes an upward acceleration of magnitude \(0.50 \text{ m/s}^2\). Find the tension at the midpoint in (a) wire A and (b) wire B.
