    need help calculating the angular velocity of each of the three hands of a clock

    im not sure where to start, thanks.

    EDIT: i might have solved it. i assume that the angular velocity is constant(assuming that the three hands are in const rotation)
    seconds hand: v = w = pi/30s^-1
    minutes hand: v = w = pi/1800s^-1
    hours hand: v = w = pi/21600s^-1
    is this right? thanks.

    Looks good to me. Just a matter of converting the time it takes to make one rotation into seconds (SI units)
