| July 9, 2021 | education
Given:
t = 2 seconds – time of body fall;
g = 9.8 m / s2 – acceleration of gravity.
It is required to determine S (meter) – the distance that the body will fly in time t.
According to the condition of the problem, the body fell freely, that is, without initial velocity (v0 = 0). Then:
S = v0 * t + g * t ^ 2/2 = 0 * 2 + 9.8 * 2 ^ 2/2 = 0 + 9.8 * 4/2 = 39.2 / 2 = 19.6 meters.
Answer: in 2 seconds of free fall, the body will fly a path equal to 19.6 meters.
