A helicopter flying horizontally with a speed of $\displaystyle 360 \mathrm{~km} / \mathrm{h}$ at an altitude of $\displaystyle 2$ km , drops an object at an instant. The object hits the ground at a point $\displaystyle \mathrm{O}, 20 \mathrm{~s}$ after it is dropped. Displacement of 'O' from the position of helicopter where the object was released is : (use acceleration due to gravity $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ and neglect air resistance)
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 2 \sqrt{2} \mathrm{~km}$
