The springs of a 1100 kg car compress 6.0 mm when its 68 kg driver gets into the driver's seat. If the car goes over a bump, what will be the frequency of vibrations?

  • Physics - ,

    6 mm = 6 * 10^-3 m

    68 * 9.81 = 667 Newtons

    k of spring = 667/(6*10^-3) = 111,167 N/m

    w = sqrt(k/m) = sqrt (111,167/1100)
    =10 radians/s

    2 pi f = w = 10
    f = 1.6 Hz
