$*$ Note that ABD and DE are not necessarily perpendicular:$*$ This will require some geometry. Both the law of sines and cosines.

Block $\backslash ($ B $\backslash )$ is able to slide vertically in a slot.

Arm DE is pinned and able to rotate about pointE. If we are given that the the angular velocity of arm DE is $\backslash (3\backslash$mathrm$\{$rad$\}/\backslash$mathrm$\{$s$\}\backslash )$ clockwise, Find the angular velocity of Arm $\backslash ($ A B D $\backslash )$ and the velocity of point $\backslash ($ A $\backslash ).$
