A brick is dropped vertically from a building at 2 m/s to reach the ground after 4s Calculate the distance the brick fell.
To calculate the distance the brick fell, we can use the formula for distance fallen due to gravity, which is given by:
distance = (1/2) * acceleration * time²
In this case, the acceleration due to gravity is approximately 9.8 m/s², and the time is 4 seconds. Substituting these values into the formula, we have:
distance = (1/2) * 9.8 m/s² * (4 s)²
= (1/2) * 9.8 m/s² * 16 s²
= (1/2) * 9.8 m/s² * 256
= 1270.4 meters
Therefore, the brick fell a distance of 1270.4 meters.
