Find the speed of fire of shot by second hunter, the distance of foot of tree from first hunter and height of bird.

The situation is as shown in figure.

A is the point of first shot.Â

With respect to A, the position of bird isÂ

Position of first shot at any instant is,Â

As both the shots hit the bird simultaneously. Therefore at the instant of hitting, positions of both the shots will be same.Â

i.e.Â Â

From conditionÂ Â we getÂ
