2m 2m Point A on the actuator shown in the figure is stationary, and point C moves at a constant speed of 2 m/s along a straight line parallel to the vector i . The angular accelerations of members AB and BC are = -1 rad/s CAB = 0 rad/s 2. aBC = 0 rad/s aAB = 1 rad/s ,2 A BC = 0 rad/s A AB = O aBC = -1 rad/s? a AB = 1 rad/s? A AB = 1 rad/s 1 rad/s? aAB = -1 rad/s %3D An answer not listed
