Physics - Kinematics 1D Question with Solution | TestHub

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