After the jump, his/her kinetic energy is, $$ E' = \frac{(p_1-\Delta p)^2}{2m_1} = \frac{p_1^2}{2m_1} - 2\frac{\Delta p\cdot p_1}{2m_1} + \frac{(\Delta p)^2}{2m_1}.$$, Writing $E$ for the previous kinetic energy, we have, $$ E' = E - 2\sqrt{E \Delta E} + \Delta E = (\sqrt E - \sqrt{\Delta E})^2 $$, $$ \frac{E'}{E} = (1 - \sqrt{\Delta E / E})^2 .$$, It is very useful to estimate the energy $\Delta E$ generated by the human in terms of the maximum height that he can jump. We've seen it in movies before, the characters are in an elevator, suddenly the lights go out, and the elevator starts to shake.
