The amplitude of oscillations of the spring pendulum is 5 cm, the mass of the load is 400 g. The maximum kinetic energy of the load is 0.05 J. Determine the natural frequency of the oscillatory system
E kin = E pot = kx ^ 2/2
k = 2Ekin / x ^ 2
w = 2 pi / t = √ k / m = √ 2 * Ekin / x ^ 2 * m = √ * 0.05 / 0.05 ^ 2 * 0.4 = 10 rad / s
We write down the answer: w = 10 rad / s.
