Homework Help: physics help please!!!

Posted by Anonymous on Sunday, March 14, 2010 at 7:27pm.

From what maximum height can a 61 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 0.65 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*10^6 N/m^2, and its smallest cross-sectional area is 2.5*10^ -4 m^2. I really need help with this problem!!!
