Question

A helicopter on a flood relief mission flying horizontally with a speed u at an altitude h , has a drop a food packet for a victim standing on the ground . at what distance from the victim shuld the food packet be dropped?

Answer 1

I think soo it's depended on helicopters capacity to come down on land by flying

Answer 2

The distance from the victim equal to R 
here value of time equal to root 2h /g 
Applying equation of motion 

R ::: Xo + ut + 1/2 at^2 

0 + u underoot 2h/g + 1/2 t^2 

R ::: u underoot 2h /g
