$${\omega }_{DB}=10rad/s$$$$v_B=150\sqrt{2}{\omega }_{DB}=1500\sqrt{2}mm/s$$$$v_{Bx}=v_B\cos 45°=1500mm/s=1.5m/s$$$$v_{By}=v_B\sin 45°=1500mm/s=1.5m/s$$$$v_{Ax}=v_{Dx}=v_{Bx}=1.5m/s$$$$v_{Ay}=0$$$$v_{Dy}=\frac{150}{150+200}\times v_{By}=\frac{3}{7}\times 1.5=\frac{4.5}{7}m/s$$$$\Rightarrow v_A=1.5m/s$$$$\Rightarrow v_D=\sqrt{1.5^2+{\left(\frac{4.5}{7}\right)}^2}=1.642m/s$$$$\Rightarrow {\omega }_{AB}=\frac{v_{By}}{150+200}=\frac{1500}{350}=\frac{30}{7}=4.286rad/s$$$${\omega }_{CA}=\frac{v_{Ax}}{150}=\frac{1500}{150}=10rad/s$$
