    360N

    Explanation:

    The frictional force = centripetal force = mass * centripetal acceleration = ma

    Since centripetal acceleration = V^2 / r

    Frictional force = mv^2 / r

    Substitute the values of m = 80kg, radius = 2m and tangential speed = 3m/s

    Frictional force = 80 * (3) ^2 / 2 = 360N
