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 0.130 m from its equilibrium position and released with zero initial speed. then after a time 0.795 s its displacement is found to be a distance 0.130 m on the opposite side, and it has passed the equilibrium position once during this interval. a. find the amplitudeb. find the period. c. find the frequency.
