Given, Horizontal distance x = 100m
velocity = 1000 m/s.
We know that t = x/v
= 100/1000
= 0.1s.
Vertical distance traveled by the bulletin 0.1s is given by,
Y = u * t + 1/2 g * t^2
= 0 * 0.1 + 1/2 * 10 * (0.1)^2
= 0 + 0.5 * (0.1)^2
= 0.05m
= 5 cm.
So, the gun should be aimed at 5cm.
hope this helps!

Answer:
Explanation:
Given, Horizontal distance x = 100m
velocity = 1000 m/s.
We know that t = x/v
= 100/1000
= 0.1s.
Vertical distance traveled by the bulletin 0.1s is given by,
Y = u * t + 1/2 g * t^2
= 0 * 0.1 + 1/2 * 10 * (0.1)^2
= 0 + 0.5 * (0.1)^2
= 0.05m
= 5 cm.
So, the gun should be aimed at 5cm above
