A block of mass \(m\) is placed on a horizontal, frictionless surface and attached to an ideal spring with spring constant \(k\). In Experiment 1, the block is pushed to compress the spring a distance \(d\) from its equilibrium position and released from rest. In Experiment 2, the same block is pushed to compress the spring a distance \(2d\) from its equilibrium position and released from rest. Let \(K_1\) be the maximum kinetic energy of the block in Experiment 1 and \(K_2\) be the maximum kinetic energy of the block in Experiment 2. Which of the following correctly compares \(K_2\) to \(K_1\) and provides a valid justification?
