In Example 7-6 in Chapter 7, we calculated the impulse and average force on the leg of a person who jumps 3.0m down to the ground. If the legs are not bent upon landing, so that the body moves a distance d of only 1.0cm during collision, determine
(a) The stress in the tibia (a lower leg bone of area = 3.0 X 10-4 m2), and
(b) Whether or not the bone will break.
(c) Repeat for a bent-knees landing (d = 50.0 cm).
