Please answer this question with explanation of of the tqtqyyqyquqyquii

Solution

Let t be the time taken by bullet to hit the target. Let h be the height of gun above the target.
s = vt
∴ 200m=(2000 ms⁻¹)×t(s)
t = 1/10 s
Now
h = 1/2 gt²
h = 1/2 x 10 x 0.1 x 0.1 =  5 cm

So answer is
5 cm above the target
