Upon impact with the ground he is brought to rest in a short time. The force experienced by his feet depends on whether he keeps his knees stiff or bends them. Find the force on his feet in each case.    A. First find the impulse on the person from the impact on the ground. Calculate both its magnitude and direction.   B. Find the average force on the feet if the person keeps his leg stiff and straight and his center of mass drops by only 1 cm vertically and 1 cm horizontally during the impact.   C. Find the average force on the feet if the person bends his legs throughout the impact so that his center of mass drops by 50 cm vertically and 5 cm horizontally during the impact.   D. Compare the results of part (b) and (c), and draw conclusions about which way is better.  You will need to find the time the impact lasts by making reasonable assumptions about the acceleration opposite to the motion. Although the force is not constant during the impact, working with constant average force for this problem is acceptable.

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)
