Question

The figure below shows a simple model of a motor vehicle that can vibrate in the vertical direction while traveling over a rough road. The vehicle has a mass of 1200 kg. The suspension system has a spring constant of 400 kN/m and a damping ratio of ζ = 0.5. If the vehicle speed is 20 km/hr, determine the displacement amplitude of the vehicle. The road surface varies sinusoidally with an amplitude of Y=0.05m and a wavelength of 6 m.

(please use the second images' conditions to answer the question above)

(Also, please submit screenshot of matlab)

(b) when = 0.1. All other values are the same.
(c) Using Matlab, plot xp(t) for 10 seconds for all three cases (Example 3.5, (a), and (b)) on the same graph.
Put a legend as well as a title and axis labels. Use the Matlab command legend().
