An aeroplane flying horizontally with a speed of
P
\( 360 \mathrm{~km} \mathrm{~h}^{-1} \) releases a bomb at a height of \( 490 \mathrm{~m} \) from
W
the ground. If \( g=9.8 \mathrm{~m} \mathrm{~s}^{-2} \), it will strike the ground at
(1) \( 10 \mathrm{~km} \)
(2) \( 100 \mathrm{~km} \)
(3) \( 1 \mathrm{~km} \)
(4) \( 16 \mathrm{~km} \)
