If an object on a horizontal frictionless surface is attached to a spring, displaced, and then released, it will oscillate. If it is displaced a distance 0.121 m from its equilibrium position and released with zero initial speed. Then after a time 0.813 s its displacement is found to be a distance 0.121 m on the opposite side, and it has passed the equilibrium position once during this interval. Part A Find the amplitude.
Part B Find the period.
Part C Find the frequency.
