A freely falling body travels __ of total distance in 5^th second

$\text{h}=\frac{1}{2}{\text{gt}}^{\text{2}}\to \left(1\right)$

${\text{S}}_{\text{n}}=\text{u}+\text{a}\left(\text{n}-\frac{1}{2}\right)$

${\text{S}}_{\text{n}}=0+\text{g}\left(5-\frac{1}{2}\right)$

${\text{h}}_{\text{n}}=\text{g}\left(5-\frac{1}{2}\right)$

$=\text{g}.\frac{9}{2}$ $\Rightarrow \frac{9\text{g}}{2}$

$\frac{{\text{h}}_{\text{n}}}{\text{h}}=\frac{\frac{1}{2}\text{g}\left(9\right)}{\frac{1}{2}\text{g}{\left(5\right)}^2}$

$\frac{{\text{h}}_{\text{n}}}{\text{h}}=\frac{9}{25}$

$\frac{{\text{h}}_{\text{n}}}{\text{h}}\times 100=\frac{9}{25}\times 100=36\%$

${\text{h}}_{\text{n}}=36\%\text{h}$
