A helicopter is flying horizontally with a speed \( v \) at an altitude \( h \) has to drop a food packet for a man on the ground. What is the distance of helicopter from the man when the food packet is dropped?
\( \sqrt{\frac{2v^{2}h}{g} + h^{2}} \)
\( \sqrt{2ghv^{2} + h^{2}} \)
\( \sqrt{\frac{2gh}{v^{2}} + h^{2}} \)
\( \frac{\sqrt{2ghv^{2} + 1}}{h^{2}} \)
