A spring stretches by 0.0226 m when a 4.39-kg object is suspended from its end. How much mass should be attached to this spring so that its frequency of vibration is f = 7.35 Hz?

7.35 = 0.0226(4.39x)

Did I set this up correctly?

  • Physics(please check) -

    The spring constant is
    k =mg/Δx=4.39•9.8/0.0226 =1903 N/m.
    Natural frequency is
    f=sqrt(k/m) sqrt (1903/4.39) = 20.8 Hz
