    Answer:

    The angular frequency of oscillation w = 21

    Explanation:

    To solve the question, we note that x(t) is the point in the motion of the object. Therefore to find the angular frequency of oscillation, we find the relationship between the angular velocity and time

    The angular frequency, ω is a scalar quantity used to depict the rate of rotation per unit time

    When there is a function in simple harmonic motion (SHM) with the following equation then ω is the angular frequency

    x(t) = A·cos (2πft) = A·cos(ωt)  which is similar to 42.5*cos(21t)

    then 21 = angular frequency
