# From what maximum height can a \( 75 \) \( \text{kg} \) person jump without breaking the lower leg bone of either leg? Ignore air resistance and assume the CM of the person moves a distance of \( 0.60 \) \( \text{m} \) from the standing to the seated position (that is, in breaking the fall). Assume the breaking strength (force per unit area) of bone is \( 170 \times 10^{6} \) \( \text{N/m}^2 \), and its smallest cross-sectional area is \( 2.5 \times 10^{-4} \) \( \text{m}^2 \). [Hint: Do not try this experimentally.]
