$$m\frac{d^2x}{dt^2} + c\frac{dx}{dt} + kx = f(t)$$ (M3.2) where m: mass, kg c: damping coefficient, Ns/m k: spring constant, N/m f: external force applied to the mass, N Fig. M3.3 Mass-spring-damping system (1) Derive a transfer function (the input F(s), and the output X(s)) based on the above math model given by Eq. M3.2. Note: It is not necessary to derive a transfer function through a state space representation. You can derive it through Laplace transform. (10 points) (2) The mass, the damping coefficient, and the spring constant are given as follows: m=2 Kg, c=6 Ns/m, and k=4 N/m. The mass is initially at rest and at the starting position which is referenced as x(0)=0. We apply the following step input: f(t)=8 N (t≥0). Derive the Laplace domain function for the output X(s). Then transform this Laplace domain function into the time domain function x(t). (20 points) (3) Find the final value of the displacement using the final value theorem. Note: Although it may be possible to find the final displacement value without using the final value theorem, it is required to use the theorem for this problem. (10 points) (4) Find the initial value of the displacement using the initial value theorem. Note: Although the initial displacement value is obvious without using the final value theorem, it is required to use the theorem for this problem. (10 points)

Solve the exponential equation. Express the solution in terms of natural logarithms or common logarithms. Then, use a calculator to obtain a decimal approximatic e<sup>x</sup> = 12.21 The solution set expressed in terms of logarithms is {ln(12.21)} (Use a comma to separate answers as needed. Simplify your answer. Use integers or decimals for any numbers in the expression. Use ln for natural logarithm and Now use a calculator to obtain a decimal approximation for the solution. The solution set is (Use a comma to separate answers as needed. Round to two decimal places as needed.)
