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

breaking force*.65=mgh
solve for h.
solve for h.

The equation above is correct, however, if they are asking about falling without breaking EITHER leg, you much double the breaking force, then multiply it by .65 and then solve for h
