1. The suspension system of a car traveling on a bumpy road has a stiffness of k = 5 x 10 N/m and the effective mass of the car on the suspension is m = 750 kg. The road bumps can be considered to be periodic half-sine waves as indicated in figure below. Determine the displacement response of the car. Assume the damping of the system to be negligible.
