At the instant shown collar B moves with a velocity of vB-3 [m/s] and acceleration ag-1.8 [m/s] tothe right. Angles B=40° and 0=20°, and length of the rod is L=500 [mm]. : Determine the magnitude of angular acceleration of rod AB, aAB [rad/s ]. Determine the magnitude of acceleration of collar A, aa [m/s*].
