    a = 16 m/s²

    Explanation:

    The mass of the object, m = 200 kg

    The radius of the circular motion, r = 4 m

    The speed of the object, v = 18 m/s

    The centripetal acceleration is given by the relation,

    a = v²/r

    Substituting the given values,

    a = 18 / 4

    = 16 m/s²

    Hence, the centripetal acceleration of the object is, a = 16 m/s²
