To calculate the angular speeds of the two bars B2 and B3, you need to use the two point formula: 1) fırst on rigid body B2 to calculate the velocity of point B (since you know velocity at point A) 2) then on rigid body B3 to calculate the velocity of point D (since you know velocity at point B) 3) Note that the velocity at point D has to be zero. Thus the two components of the velocity are zero giving you two equations to solve for the two unknown angular velocities.
