Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

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.

The combined thrust and lift force on the airplane applied at the end of the static hover can be expressed as F = (44t + 2500t2)i + (250t2 + t + 176 580)j, where F and t are expressed in newtons and seconds, respectively. Determine how long it will take the airplane to reach a cruising speed of 1000 km/hr (cruising speed is defined to be in the x-direction only).
