Compressive strength of our bones is important in everyday life. Young's modulus for bone is about 1.41010Pa. Bone can take only about a 1.0% change in its length before fracturing. Estimate the maximum height from which a 70kg man could jump and not fracture the tibia. Take the time between when he first touches the floor and when he has stopped to be 0.006s, and assume that the stress is distributed equally between his legs
