Chapter 8, Problem 27PQ

A spring of spring constant k lies along an incline as shown in Figure P8.27. A block of mass m is attached to the spring. The spring compresses, and the block comes to rest as shown. Find an expression for the change in the Earth–block–spring system’s potential energy in terms of the parameters given in the figure.
