At the instance shown below, the base of the robotic arm rotates about the Z axis with an angular velocity of w = 5 rad/s, which is increasing at 3 rad/s. Also, the boom BC rotates with an angular velocity of WBC 7 rad/s, which is increasing at 2 rad/s. = Determine the speed VC of the part C held in the arm's grip at this instant. Give the answer in units of m/s. 0.7 m A = 5 rad/s w = 3 rad/s B WBC = 7 rad/s WBC = 2 rad/s 0.5 m
