A helicopter on a flood relief mission flying horizontally with a speed u at an altitude `h`, has to drop a food packet for a victim standing on the ground. At what distance form the victim should the food packet be dropped.

Text Solution

Verified by Experts

In figure `H`, represents positions of the helicopter and `V` that of the victim. For vertical motion of the packet

`S =ut +½ at^(2)`
`h = 0+(1)/(2) "gt"^(2)` or `t = sqrt((2h)/(g))`
Horizontal distance conved by the food packet in
thus t`, x = ut u sqrt((2h)/(g))`
Now the distance of the point of projection from the food packet is
`D = sqrt(h^(2) +x^(2)) = sqrt(h^(2) +(2u^(2)h)/(g))`
