There are two points P and Q on a planar rigid body. The relative velocity between the two points

Mobility of a statically indeterminate structure is

For the configuration shown, the angular velocity of link AB is $$10$$ rad/s counterclockwise. The magnitude of the relative sliding velocity (in ms^-1) of slider B with respect to rigid link CD is
