A block of mass \(m\) is attached to an ideal horizontal spring with spring constant \(k\) and oscillates with amplitude \(A\) on a frictionless horizontal surface. The equilibrium position of the block corresponds to \(x = 0\). The block passes through four marked positions: Position 1 at \(x = -A\), Position 2 at \(x = -\dfrac{1}{2}A\), Position 3 at \(x = 0\), and Position 4 at \(x = +\dfrac{1}{2}A\). Which of the following correctly ranks the kinetic energies \(K_1\), \(K_2\), \(K_3\), and \(K_4\) of the block at these four positions?
