Worked example problem on potential energy diagrams. You are encouraged to challenge and test your knowledge by first attempting the problem and then comparing your answer.

A rock with a mass of 1 kg is attached to a rubber slingshot, which is stretched to an initial position of 15 cm. The variation of force with distance is shown. Find an expression for the potential energy stored in the rubber and determine the speed of the rock when it reaches 10 cm.
