QUESTION #4.8| A system of differential equations is created for two masses connected by springs between one another, and connected to opposite walls. The dependent variables form a 4 x 1 vector y consisting of the displacement and velocity of each of the two masses. For the system y' = Ay, the matrix A is given by 1 1 -10 8 -6 -10 -6 Because the system oscillates, there will be complex eigenvalues. Find the eigenvalue associated with the following eigenvector -5i 5i 15 + 15i -15 - 15i
