    a=v²/r; F=ma

    v=10m/s

    r=5m

    m=10kg

    a=10²/5m/s²=20m/s²

    F=10*20N=200N.

    f = mV²/r = (10)(10)²/(5) = 1000/5 = 200 N

    Centripetal force f = mV²/r = mrω²

    ω is angular velocity in radians/sec

    1 radian/sec = 9.55 rev/min

    m is mass in kg

    r is radius of circle in meters

    V is the tangental velocity in m/s

    f is in Newtons
