10.21.Model:Assume an ideal spring that obeys Hooke’s law. There is no friction, so the mechanical energy sKU+is conserved. Also model the book as a particle. Visualize:The figure shows a before-and-after pictorial representation. The compressed spring will push on the book until the spring has returned to its equilibrium length. We put the origin of our coordinate system at the equilibrium position of the free end of the spring. The energy bar chart shows that the potential energy of the compressed spring is entirely transformed into the kinetic energy of the book.
