As part of a packing and distribution system, boxes are dropped onto a spring and pushed onto a conveyor belt. The boxes are originally at a height h above the uncompressed spring [Figure P7.20(a)]. Once dropped, the box of mass m compresses the spring a distance ΔL [Figure P7.20(b)]. If all the potential energy of the box is converted into elastic energy in the spring, find an expression for ΔL.
