An object of mass m = 8.0 kg is attached to a massless spring described by Hooke's law and allowed to hang in Earth's gravitational field. The spring stretches 2.2 cm as the object reaches its equilibrium position. If it were now allowed to oscillate on this spring, what would be its frequency?

3.4 Hz

1.6 Hz

0.28 × 10-3 Hz

0.52 Hz

If a 1 kg object on a horizontal, frictionless surface is attached to a spring, displaced, and then released, it will oscillate. If it is displaced 0.120 m from its equilibrium position and released with zero initial speed. After 0.8 s its displacement is found to be 0.120 m on the opposite side, and it has passed the equilibrium position once during this interval. Find the amplitude, the period, the frequency, the angular frequency and the spring constant.
