Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_285

3/285 The two 0.2-kg sliders are connected by a light rigid bar of length $L = 0.5\text{ m}$. If the system is released from rest in the position shown with the spring unstretched, plot the speeds of $A$ and $B$ as functions of the displacement of $B$ (with zero being the initial position). The 0.14-MPa air pressure acting on one $500\text{-mm}^2$ side of slider $A$ is constant. The motion occurs in a vertical plane. Neglect friction. State the maximum values of $v_A$ and $v_B$ and the position of $B$ at which each occurs.
