The body fell from a height of 100 meters. Find how long it took it to cover the second half of its journey (50 meters).

Task data: h (total fall height) = 100 m; h2 (remaining height) = 50 m.

Constants: g (acceleration due to gravity) ≈ 10 m / s2.

To find the duration of the body’s fall on the last 50 meters, we will use the formula: t2 = t – t1 = √ (2h / g) – √ (2 * h1) / g) = √ (2h / g) – √ (2 * (h – h2) / g).

Let’s calculate: t2 = √ (2 * 100/10) – √ (2 * (100 – 50) / 10) = 1.31 s.

Answer: The body will fly the last 50 meters in 1.31 s.
