At the instant shown in (Figure 1), rod AB has an angular velocity WAB = 2.2 rad/s and an angular acceleration AB = 10 rad/s². The collar at C is pin-connected to CD and slides over AB. Part A Determine the angular velocity of rod CD at this instant. Express your answer in radians per second to three significant figures. Enter positive value if the direction of velocity is counterclockwise and negative value if the direction of velocity is clockwise. Figure 60° WAB αAB 0.75 m Do 0.5 m 1 of 1 ΜΕ ΑΣΦ.
