A weight W is suspended from a vertical spring whose modulus is “K” N/m. The weight is pulled down “S” m from its equilibrium and then released. Determine its velocity when it returns to its equilibrium position.
A wire of length L, Young’s modulus Y, and crosssectional area A is stretched elastically by an amount ΔL. By Hooke’s law, the restoring force is -k ΔL. (a) Show that k = YA/L. (b) Show that the work done in stretching the wire byan amount ΔL is W = 1/2 YA(ΔL)2/L .

This ligament is much more elastic than a typical ligament, stretching from 15% to 45% longer than its resting length as a horse’s head moves up and down while it runs.
