Solve the following problems for all t> 0 using the Laplace transform. State the "forced response" and the "free response" separately. Recall: the forced response is the part of the response due to the forcing function (the right hand side in standard form) and the free response is the part of the response due to initial conditions. Do not combine the two parts of the response. x(0) = 1/3, (0-) = -3 x(0) = 5, (0) = 8 (a) + 9x + 8x = = 208(t) (b) 2x + 12x + 18x = = 308(t) (c) + 4x = 308(t) (d) x + 12x + 40x = 688(t) x(0) = 5, (0) = 12 x(0)=0, x(0) = 100
