A horizontal bar of mass m₁ and small diameter is suspended by two wires of length l from a carriage of mass m₂ which is free to roll along the horizontal rails. If the bar and carriage are released from rest with the wires making an angle θ with the vertical, determine the velocity v_b/c of the bar relative to the carriage and the velocity v_c of the carriage at the instant when θ = 0. Neglect all friction and treat the carriage and the bar as particles in the vertical plane of motion.
