Consider a spring-mass-damper system with mass m, spring constant k, and damping coefficient c. The differential equation describing the motion of the mass is: d^2x/dt^2 + kx = 0 where x denotes the displacement of the mass from its rest position and t denotes the time variable. Given m = 1 kg, c = 1 Ns/m, and k = 9.25 N/m, x(0) = 2 m and x'(0) = 8 m/s.
