People jump from much greater heights than this, explain how this is possible

a) If a person flexes her legs on landing, the energy is transformed not only into elastic energy in the bones, but also into elastic energy in other tissues and into thermal energy.

b) For a jump from greater height the air resistance significantly reduces the speed of the bogy just before the landing.

c) Significant part of kinetic energy of the body just before the landing is absorbed by shoes during the landing

    a

    Explanation:

    When people jump from greater height, energy gets absorbed into the muscles as potential. And when the person flexes her legs on landing energy is trans formed not only into elastic energy in the bones, but also into elastic energy in other tissues and into thermal energy.

    air resistance is very small hence, negligible. So, the statement a is correct and rest are wrong.
