705.6 m

Explanation:

time, t = 12 sends

initial velocity, u = 0

Acceleration due to gravity, g = - 9.8 m/s^2

As the object is falling freely so the initial velocity is zero.

Let the distance traveled by the body is h in time t = 12 s.

Use second equation of motion

$h = u t - 1/2 gt^{2}$

Ad the distance is downwards so take it as negative

So, $-h = 0 - 1/2\times 9.8 \times 12 \times 12$

h = 705.6 m

Thus, the distance traveled in 12 second is 705.6 m
