An object of mass $\displaystyle 5$ kg is thrown vertically upwards from the ground. The air resistance produces a constant retarding force of $\displaystyle 10$ N throughout the motion. The ratio of time of ascent to the time of descent will be equal to : $\displaystyle \left[\right.$ Use $\displaystyle \left.\mathrm{g}=10 \mathrm{~ms}^{-2}\right]$.
Official answer
(2)
$\displaystyle \sqrt{2}: \sqrt{3}$
