From given the data:
Range R = 2 ⨯100 m = 200 m
Initial velocity u = 500 m/s

Horizontal distance x = 100 m
Velocity v = 500 m.s^-1
Time taken to travel this distance t = x/v = 100/500 = 1/5s
Vertical distance travelled by the bullet in time 1/5s is given by,



If the person directly aims at the bird, the bullet will hit 20 cm below the bird. Thus the gun must be aimed at 20 cm above the position of the bird.

Let @ be the angle of projection In this question range = 100m , velocity(v) = 500 , g=10 we know , range = (v^2/g) sin2@ therefore , (500^2/10) sin2@ = 100 sin2@ = 0.004 As sin2@ is small, so take sin2@~= 2@ 2@ = 0.004 => @ =0.002 The height above the bird which must be aim = (range) x (tan@) => 100(0.002) = 0.2m = 20cm Hope you have got your answer ...pls upvote
