The system of Prob. 5/84 is repeated here. If the vertical rod has a downward velocity v = 0.8 m/s and an upward acceleration a = 1.2 m/s² when the device is in the position shown, determine the corresponding angular acceleration a of bar AB and the magnitude of the acceleration of roller B. The value of R is 0.4 m.
