    The only given information is the time in 3 seconds. We are asked to find the position, or the distance traveled. The working equation to be used here is:

    x = v₀t + 1/2 at²

    where

    x is the distance

    v₀ is the initial velocity

    a is the acceleration

    In order to solve this, let's assume the object is free falling. So v₀ = 0 and a = 9.81 m/s².

    x = 0 + 1/2 (9.81) (3) ²

    x = 44.145 meters
