Assuming that the rope does not slip relative to any of the pulleys in the system, determine the velocity and acceleration of A and D, knowing that the angular velocity and acceleration of pulley B are ωB = 7 rad/s and αB = 3 rad/s2, respectively. The diameters of pulleys B and C are d = 25 cm and ℓ = 34 cm, respectively.
