The period of motion of an object-spring system is T = 0.474 s when an object of mass m = 296 g is attached to the spring.

(a) Find the frequency of motion in hertz.

(b) Find the force constant of the spring.

(c) If the total energy of the oscillating motion is 0.150 J, find the amplitude of the oscillations.

  • Physics -

    (a) f = 1/T = 2.11 Hz

    (b) 2*pi*f = 13.26 radians/s = sqrt(k/m)
    m = 0.296 kg
    Solve for k
    (c) (1/2)kA^2 = 0.150 J
    Solve for amplitude A, in meters
