A block of mass \(m\) is held at rest at a height \(H\) above an uncompressed, ideal vertical spring of spring constant \(k\), as shown in Figure 1. The bottom of the spring is fixed to the floor. At time \(t = 0\), the block is released. The block falls, contacts the spring, and compresses it. Air resistance is negligible, and the block is not attached to the spring.
