2. The figure below shows a highly simplified version of an automobile suspension system. The displacement y is measured from the static equilibrium position in the absence of the input u. 0 m y P Figure 2. Automobile suspension system. a) Assuming that the motion u at point P is the input to the system and the vertical motion y of the body is the output, obtain the transfer function Y(s)/U(s). b) Form 1 kg, b = 1 N-s/m, and k = 4 N/m, sketch the magnitude frequency response and phase frequency response using asymptotic approximations (do not use MATLAB).
