3. A spring mass system with friction has mass m = 2 kg, friction constant a = 4 kg/sec, and Hooke's constant k = 6 kg/sec?. The spring mass system has 2nd order homoge- neous differential equation given by the following: yl" + 2y' + 3y = 0, y(0) = 2 m, y' (0) = 3 m/sec (a) Write the down the differential matrix equation for the corresponding system of first order ODES and find the eigenvalues. (b) Find the eigenvectors corresponding to each of the eigenvalues. (c) Find the general solution, 7(t), using the given initial conditions.
