Question

If an 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, then after 0.800 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 (a) the amplitude; (b) the period; (c) the frequency. 14.3 . The tip of a tuning fork go

    Answer:

    A) 0.120

    B) 1.6s

    C) 0.625 Hz

    Explanation:

    Here, X = 0.120 m

    x = 0.120 m after t = 0.800 s

    A- Amplitude = max displacement from equillibrium position = 0.120 m

    B- Period = 2 * 0.800 = 1.6 s

    C- Frequency = 1/peroid = 1/1.6

    f = 0.625 Hz
