    Centripetal acceleration is the motion inwards towards the center of a circle. It is given by the square of velocity, divided by the radius of the circular path.

    ac = v²/r, where ac is the centripetal acceleration in m/s²

    Therefore,

    Centripetal acceleration = 3²/20m

    = 9/20m

    = 0.45 m/s²

    Thus, the centripetal acceleration is 0.45 m/s²
