I just have problems with finding the parameters c and k thank you

3. Consider a mass m = 1kg connected by a spring with spring constant k > 0 (in N/m), no external force and damping coefficient c> 0 (in Ns/m). The trajectory of the mass r(t) (in meters) at time t (in seconds) is a solution of of the equation 3:" + cx' + kx = 0 (a) Load the file data.mat into your MATLAB workspace. There are vectors t and x represent- ing the solution z(t). Plot the data x versus t using the MATLAB command plot(t,x). The plot corresponds to a function of the form x(t) = Aer cos(wt + o) Determine the values of the parameters A, a, w and 6 and save the values as parameter_A, parameter_alpha, parameter_omega, and parameter_phi. (b) Determine the values of the parameters c and k and save the values as parameter_c and parameter_k. 3.
