In the pulley and cable system shown below, block B is connected with an electrical motor via a cable/cord. Motor winds the cable and point A moves in the direction shown. a) Define the position coordinates and write the equation of total length of the cable/cord b) Establish the relation between velocities of point A and Block B c) If the speed of the cable coming onto the motor pulley is 12 m/s, determine the speed of block B.
