    What was the bullet's speed as it left the barrel?
    A rifle is aimed horizontally at a target 48.0 m away. The bullet hits the target 2.70 cm below the aim point.
    What was the bullet's flight time?
    What was the bullet's speed as it left the barrel?

    Can someone answer this question for me please.
    Thanks.

    Use to find the time of flight of your bullet.

    a is the acceleration due to gravity.

    With that time, you can find the horizontal velocity of the bullet since you know the time and the horizontal displacement.

    Post your answers, and we'll tell you whether you really understood the question. :)
