Even if, by some miracle, you jumped at precisely the right moment, would you be able to walk awayunscathed? [insert object name]) in real life to get things done. Read more: 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.
