Question

An aeroplane flying horizontally with a velocity of 216 km h-1 drops a food packet while flying at a height of 490 m. The total horizontal distance travelled by the packet is

Answer 1

Answer:-

Given

Speed of aeroplane,u = 216 km/h=216x5/18=60 m/s

Height,h=490m

Let R be the horizontal distance.

we know,

$r = u \sqrt{ \frac{2h}{g} } \\ = 60 \sqrt{ \frac{2 \times 490}{9.8} } \\ = 60 \times \sqrt{100} \\ = 60 \times 10 \\ = 600m$

Hence the horizontal distance is 600m.
