In Example  in Chapter 7, we calculated the impulse and average force on the leg of a person who jumps  down to the ground. If the legs are not bent upon landing, so that the body moves a distance  of only  during collision, determine

(a) the stress in the tibia (a lower leg bone of area = \(3.0 \times 10^{-4} \mathrm{~m}^{2}\)) and

(b) whether or not the bone will break.

(c) Repeat for a bent-knees landing \((d=50.0 \mathrm{~cm})\).
