A stone D of mass $m_D = 4$ kg strikes the uniform slender rod ABC of $m_{rod} = 20$ kg with a velocity of $V_D = 10$ m/s. If the stone remains attached to the rod,
determine the angular velocity of the rod just after impact and the maximum angle of swing before the rod momentarily stops. The stone has a negligible size.
