Two spheres of mass m are connected to each other by a spring and rods of negligible weight. The rods can rotate freely at their connection points. Spheres can slide freely in both directions on the inclined plane. Find the aAcceleration of point C in the middle of the arc.(m=3kg,?=30o,?=200?/?,?=200?)
