Question

A brick is dropped vertically from a building at 2 m/s to reach the ground after 4s Calculate the distance the brick fell.

Answer 1

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.
