An aeroplane moving horizontally with a speed of $180km/hr$ drops a food packet while flying at a height of $490m$. The horizontal range of the packet is:

The correct options are
A $180m$
B $670m$
C $500m$

Time taken by packet to arrive on the ground t

$h=0\times t+\frac{1}{2}g{t}^{2}t=\sqrt{\frac{2h}{g}}=\sqrt{\frac{2\times 490}{9.8}}=\sqrt{100}=10sec.$

Distance traveled by the packet in horizontal direction during the same time D

$D=u\times t=180\times \frac{5}{18}\times 10=500m$
