The body began to fall from a height of 30 m. At what height in m will it be in 2 s?

To find the value of the height at which the falling body should be in 2 seconds, we use the formula: h = h0 – h1 = h0 – g * t ^ 2/2.

Variables and constants: h0 – initial body height (h0 = 30 m); g – acceleration due to gravity (g ≈ 10 m / s2); t is the duration of the fall (t = 2 s).

Calculation: h = h0 – g * t ^ 2/2 = 30 – 10 * 2 ^ 2/2 = 10 m.

Answer: After 2 s of the fall, the given body will be at a height of 10 m.
