What allows us to make the determination that the boxes arent moving at the same velocity after being released from rest? It seems to me we would base this off of each boxes resistance to friction, but in this problem they are moving on a smooth surface. And then in this problem, we consider the boxes to move at the same velocities after the spring is released? Please explain how we can make this judgement. This is the problem: The two blocks A and B each have a mass of 5 kg and are suspended from parallel cords. A spring, having a stiffness of k=60 N/m is attached to B and is compressed 0.3 m against A and B as shown. Determine the maximum angles θ\thetaθ and ϕ\phiϕ of the cords when the blocks are releasedfrom rest and the spring becomes unstretched.
