The motion of a damped spring-mass system as give is described by the following ordinary differential equation: m d²x dx + c dt2 dt + kx = 7 where x = displacement from equilibrium position (m), t =time in second, m =10 kg mass and c = the damping coefficient (N s/m). The damping coefficient c take on the value of 200 (overdamped) and the spring constant k = 15 N/m. The initial velocity is zero and the initial displacement x = 3 m. Find the displacement r(t) using Laplace transforms method. Then, calculate x(t) for t= 5, 10, 15 seconds. (a)
