Manufactured items are spray-painted as they pass through the automated work station shown. Knowing that the bent pipe ACE rotates at the constant rate ω1 = 0.4 rad/s and that at Point D the paint moves through the pipe at a constant relative speed u = 150mm/s, determine, for the position shown, (a) the velocity of the paint at D, (b) the acceleration of the paint at D.
