Each of the sliders A and B has a mass of 2.2 kg and moves with negligible friction in its respective guide, with y being in the vertical direction. A 29-N horizontal force is applied to the midpoint of the connecting link of negligible mass, and the assembly is released from rest with $\theta$ = 0. Calculate the speed v with which A strikes the horizontal guide when $\theta$ = 90°. 0.49 m 29 N 0.49 m B Answer: v = i m/s
