A rifle is aimed horizontally at a target 46.0away. The bullet hits the target 2.30 below the aim point.
What is the bullet's flight time?
What is the velocity as it leaves the barrel?
Your numbers need dimensions. Are they in meters? Is the 2.30 in centimeters? Do you want the bullet speed in m/s?
For the flight time, figure out how long it takes a dropped object to fall 2.30 whatevers.
