Hey, the bullet is not falling in the direction of the initial velocity. The bullet is falling due to gravity, downward, falling for a distance of 1.8 meters.
You do the vertical falling distance to get time in the air, then use that time to calculate how far horizontally the bullet went.
for this question
A bullet is fired from a rifle that is held 1.8 m above the ground in a horizontal position. The initial speed of the bullet is 1120 m/s. Find
why is the equation just (.5)(9.8)(t^2)=1.8
why don't we have to take in account for initial velocity:
(.5)(a)(T^2)+(Vinitial)(T)=(delta distance) ????
