Question

Two bullets are fired simultaneously, horizontally and with different speeds from the same place. Which bullet will hit the ground first?

• A. The faster bullet
• B. The slower bullet
• C. Both will hit simultaneously
• D. Depends on the masses

Answer 1

Answer: (C)

When two bullets are fired simultaneously, horizontally with different speeds, then they cover different horizontal distance because there is no acceleration in this direction.
$Since,horizontaldistance\left(R\right)=velocity\times time.$
But there is a vertical acceleration towards the earth (g), so the vertical distance covered by both bullet is given by:
$y=\frac{1}{2}g{t}^2$ , which independent of the initial velocity.
So, both the bullets will hit the ground simultaneously.
