A spring is such that a force of 20 [N] would stretch it 0.2[m]. The spring hangs vertically and a 4 [kg] mass is attached to the end of it. After this mass comes to rest in its equilibrium position, it is pulled down [0.4 [m] below this position and then released at t = 0. The medium offers a resistance 2dx/dt, where dx/dt is the instantaneous velocity in [m/s] (a) Determine the displacement of the weight as a function of the time and express this displacement in the amplitude-phase form (b) Find the so-called "period" and determine the logarithmic decrements. (c) At what time does the weight first pass through its equilibrium position?

A vibrator, pulley, and hanging object are arranged as in Figure P18.219(attachment) with a compound string, consisting of two strings of different masses and lengths fastened together end-to-end. The first string, which has a mass of 1.56 g and a length of 61.0 cm, runs from the vibrator to the junction of the two strings. The second string runs from the junction over the pulley to the suspended 7.02 kg object. The mass and length of the string from the junction to the pulley are, respectively, 6.75 g and 100.3 cm. a) Find the lowest frequency for which standing waves are observed in both strings, with a node at the junction. The standing wave patterns in the two strings may have different numbers of nodes. b) What is the total number of nodes observed along the compound string at this frequency, excluding the nodes at the vibrator and the pulley?
