The velocity of roller A is v_A = 0.5 m/s to the right as shown, and this velocity is momentarily decreasing at a rate of 2 m/s². Determine the corresponding value of the angular acceleration a of bar AB as well as the tangential acceleration of roller B along the circular guide. The value of R is 0.6 m.
