How long after the beginning of the body’s fall from rest its velocity will be 40ms. From what height did the body fall?

g = 9.8 m / s2 – acceleration of gravity.

Let’s calculate the time required for the speed of the falling body to reach 40 m / s:

t = v / g = 40 / 9.8 = 4.08 s;

Let’s calculate the distance traveled by the body during the fall:

S = gt ^ 2/2 = (9.8 * 4.08 ^ 2) / 2 = 81.57 m.

Answer: t = 4.08 s; S = 81.57 m.
