Question: A bungee cord is essentially a very long rubber band that can stretch up to four times its unstretched length. However, its spring constant varies over its stretch [see Menz, P.G. “The Physics of Bungee Jumping.” _The Physics Teacher_ (November 1993) 31: 483-487]. Take the length of the cord to be along the _x_ -direction and define the stretch _x_ as the length of the cord _l_ minus its un-stretched length l_{0}; that is, x = l - l_{0} (see below). Suppose a particular bungee cord has a spring constant, for 0 \leq x \leq 4.88\ \text{m} , of k_{1} = 204\ \text{N/m} and for x \geq 4.88\ \text{m} , of k_{2} = 111\ \text{N/m}\text{.} (Recall that the spring constant is the slope of the force _F(x)_ versus its stretch _x_ .) (a) What is the tension in the cord when the stretch is 16.7 m (the maximum desired for a given jump)? (b) How much work must be done against the elastic force of the bungee cord to stretch it 16.7 m?  Figure 7.16 (credit: modification of work by Graeme Churchard)
