P$3\mathrm{.}20$ In Figure $3\mathrm{.}58,$ a disk is pin connected to the ground and to an L$-$shaped link, which is in contact with a wedge attached to the ground. Assuming that the Lshaped link remains in contact with the wedge, find the velocity of point C at the configuration shown in Figure $3\mathrm{.}58$ if the disk is rotating counterclockwise with a spedd of $6ra\frac{d}{s}.($answer: $||V||=25\mathrm{.}27\frac{m}{s}.)$
