The two 0.2-kg sliders Aand Bare connected by a light rigid bar of length . If the system isreleased from rest while in the position shown with the spring undeformed, determine the maximum compression of the spring. Note the presence of a constant 0.14-MPa air pressure acting on one 500-mm2 side of slider A. Neglect friction. Themotion occurs in a vertical plane.
