Question

A gun is aimed at a target in line of its barrel. The target is released & allowed to fall under gravity at the same instant the gun is fired. Given sufficient space, the bullets will _____.


A

pass above the target

loader
B

pass below the target

loader
C

hit the target

loader
D

certainly miss the target

loader

Solution

The correct option is D

hit the target


Initially, both have the same vertical initial velocity, i.e. = 0. After time t, bullet would have covered the same vertical distance as covered by the target because for both of them,
    u = 0
    a = -g
So, given sufficient space, the bullet will hit the target, no matter what's its horizontal velocity may be.
