Chapter 22, Problem 22.15(choose chapter or problem)
The motion of a damped spring-mass system (Fig. P22.15) is described by the following ordinary differential equation: m d2x dt2 + c dx dt + kx = 0 where x = displacement from equilibrium position (m), t = time (s), m = 20-kg mass, and c = the damping coefficient (N s/m). The damping coefficient c takes on three values f 5 (underdamped), 40 (critically damped), and 200 (overdamped). The spring constant k = 20 N/m. The initial velocity is zero, and the initial displacement x = 1 m. Solve this equation using a numerical method over the time period 0 t 15 s. Plot the displacement versus time for each of the three values of the damping coefficient on the same plot.
