Horizontal oscillation of the spring-loaded plunger e is controlled by varying the air pressure in the horizontal pneumatic cylinder f. if the plunger has a velocity of 1.6 m/s to the right when θ = 29°, determine the velocity of roller d (positive if up, negative if down) in the vertical guide and find the angular velocity ω (positive if counterclockwise, negative if clockwise) of abd for this position.
