A bomb is dropped by an aero plane flying horizontally with a velocity \(200 \mathrm{~km} / \mathrm{hr}\) and at a height of \(980 \mathrm{~m}\). At the time of dropping a bomb, the distance of the aero plane from the target on the ground to hit directly is \(\left(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2\right.\) )

The plane is flying horizontally. Hence initial vertical component of the velocity is zero.
If it reaches the ground in time \(t\), then
\( \begin{aligned} & \mathrm{h}=\frac{1}{2} \mathrm{gt}^2 \\ & \mathrm{t}^2=\frac{2 \mathrm{~h}}{\mathrm{~g}}=\frac{2 \times 980}{9.8}=200 \\ & \mathrm{t}=10 \sqrt{2} \mathrm{~s} \end{aligned} \)
The horizontal component of the velocity is
\(\mathrm{V}=200 \mathrm{~km} / \mathrm{hr}=200 \times \frac{5}{18}=\frac{1000}{18} \mathrm{~m} / \mathrm{s}\)
The horizontal distance to be covered is
\(\mathrm{d}=\mathrm{Vt}=\frac{1000}{18} \times 10 \sqrt{2}=\frac{10^4}{9 \sqrt{2}} \mathrm{~m}\)
