Step-by-step explanation:
We know that
As the packet simply gets dropped, it's initial vertical velocity u = 0
Time taken for the packet to reach ground is
T =√(2H/g) = √(2*396.9/9.8) = √81 = 9s
Horizontally the packet travels at the speed of aeroplane,
V = 720kmph = 720*(5/18) = 200m/s
Range R = V*T = 200*9 = 1800m
