A diagram showing a rectangular block labeled 'm' held at a height 'H' above a vertical spring. The spring is labeled 'k' and its bottom is attached to a horizontal floor. A dashed horizontal line indicates the top of the uncompressed spring, and a vertical arrow labeled 'H' points from the dashed line up to the bottom of the block.
Figure 1. A block of mass \(m\) released from height \(H\) above a spring.
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.
