A bullet is launched horizontally at speed $v$ from a rifle. During a brief time $t$ after it leaves the rifle, gravity is the only force acting on its motion. The acceleration of free fall is $g$. Which expression gives the horizontal distance travelled in time $t$ divided by the vertical distance travelled in time $t$?
- A$\frac{vt}{g}$
- B$\frac{v}{gt}$
- C$\frac{2vt}{g}$
- D$\frac{2v}{gt}$
