Question
Two bullets are fired simultaneously, horizontally and with different speeds from the same place. Which bullet will hit he ground first?
Options
the faster one
the slower one
both will reach simultaneously
depends on the masses.

Solution
both will reach simultaneously
Because the downward acceleration and the initial velocity in downward direction of the two bullets are the same, they will take the same time to hit the ground and for a half projectile.
Time of flight = T =\[\sqrt{\frac{2h}{g}}\] .
