B. From what maximum height can a 70 kg person jump without breaking the lower leg bone on either leg? Ignore air resistance and assume the body of the person moves a distance of 5 cm form the standing to the seated position in breaking the fall. Assume the strength (force per area) of bone is 170 x 10°N/m² , and its smallest cross-sectional area is 2.5 x 10-4m² .
