20-41. At the instant shown, the arm AB is rotating about the fixed pin A with an angular velocity o = 4 rad/s and angular acceleration ở = 3 rad/s. At this same instant, rod BD is rotating relative to rod AB with an angular velocity wz =5 rad/s, which is increasing at w,=7 rad/s. Also, the collar Cis moving along rod BD with a velocity of 3 m/s and an acceleration of 2 m/s', both measured relative to the rod. Determine the velocity and acceleration of the collar at this instant. w = 4 rad/s in = 3 rad/s? 1.5 m 3 m/s 2 m/s2 w, = 5 rad/s iz = 7 rad/s? 0.6 m
