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 {{{2gh{v^2} + 1} \over {{h^2}}}} $
$\sqrt {2gh{v^2} + {h^2}} $
$\sqrt {{{2{v^2}h} \over g} + {h^2}} $
$\sqrt {{{2gh} \over {{v^2}}} + {h^2}} $
