Arifle is aimed horizontally at a target 49 m away. the bullet hits the target 2.3 cm below the aim point. part a what was the bullet's flight time? neglect the air resistance.

We use the equation of motion for vertical component,

Here,   is displacement of bullet,  is vertical initial velocity of bullet which is equal to zero because bullet was fired horizontally, and t is time of flight.

Therefore,

Given,

Substituting the values, we get time of flight
