How many seconds will the body fall from a height of 180 m.

H = 180 meters – the height from which the body will fall;

g = 10 meters per second squared – gravitational acceleration (constant near the Earth’s surface).

It is required to determine t (seconds) – the time of the body falling.

Since it is not specified in the problem statement, we assume that the body began to fall without an initial velocity. Then:

H = g * t ^ 2/2, hence:

t = (2 * H / g) ^ 0.5 = (2 * 180/10) ^ 0.5 = (360/10) ^ 0.5 = 36 ^ 0.5 = 6 seconds.

Answer: from a height of 180 meters, the body will fall for 6 seconds.
