A ball is thrown up vertically with a certain velocity so that, it reaches a maximum height $\displaystyle h$.
Find the ratio of the times in which it is at height $\displaystyle \frac{\mathrm{h}}{3}$ while going up and coming down respectively.
Official answer
(2)
$\displaystyle \frac{\sqrt{3}-\sqrt{2}}{\sqrt{3}+\sqrt{2}}$
