Homework Statement

Ok, well I have a Grade 11 Physics question regarding Projectile Motion Calculations. The question is: A bullet is shot horizontally from a gun. If the bullet's speed exiting the muzzle is 325 m/s and the height of the gun above the ground is 2.0m,

a) how long was the bullet in the air?

The Attempt at a Solution

I see that a) is looking for the time. As well as, I have 325 which I assume is the velocity and 2.0m which I assume is the distance. Now this is the part I am stuck on. Which formula do I use to find Time? Sorry if my question seems stupid. I'm just in need for some help.

Thanks

Think about what the problem is asking you. Does the time it takes for the bullet to fall vertically depend on how fast it is moving horizontally?

Hmm ... well I guess it would? Sorry I'm a physics noob.

The legend
nope it doesnt. it just depends on vertical direction.....now do you get a clue?

It is basically a free fall problem.
