You are to investigate the vibration properties of the shock absorber system of a 2000 kg car. The shock absorbers drop 10 cm when the car is lowered from the lift and stands on its wheels. In addition, the amplitude decreases by 50% with each oscillation. Assume that the weight of the car is distributed evenly over all wheels and use the above information to determine the values for the spring constant k and the damping coefficient b. What error does the calculation deliver if the natural frequency of the shock absorbers ω is approximated by that of the undamped system ω_0?
