A rifle is aimed horizontally at a target 50m away, the bullet hits the target 0.02m below the aim point what is the bullets flight time?

time to fall .02m:

h=1/2 g t^2, or t=sqrt(2*.02/9.8) seconds

To determine the bullet's flight time, we need to consider the horizontal distance it travels and the vertical distance it falls.

First, let's calculate the horizontal distance the bullet travels. Since the rifle is aimed horizontally, this distance is simply the same as the target distance, which is 50 meters.

Next, we need to calculate the vertical distance the bullet falls. It is given that the bullet hits the target 0.02 meters below the aim point. This means the bullet has fallen 0.02 meters over the 50-meter horizontal distance.

To find the flight time, we can use the formula for vertical motion, which relates the distance fallen (vertical displacement) to the acceleration due to gravity (9.8 m/s^2) and the time taken (flight time).

The formula for vertical motion is:

d = (1/2) * g * t^2,

where:
d = vertical displacement (0.02 meters),
g = acceleration due to gravity (9.8 m/s^2),
t = flight time (unknown).

Rearranging the formula, we get:

t = √(2 * d / g).

Substituting the values into the formula, we have:

t = √(2 * 0.02 / 9.8) seconds.

Calculating this equation, we find:

t ≈ 0.020 seconds.

Hence, the bullet's flight time is approximately 0.020 seconds.
