Icicle fell from the roof and flew to the ground in 3 seconds. What is the height of the building?
| June 10, 2021 | education
To calculate the required building height, we use the formula: S = h = a * t ^ 2/2 = g * t ^ 2/2.
Constants and variables: g – gravitational acceleration (g ≈ 10 m / s2); t is the flight time of the icicle to the ground (t = 3 s).
Calculation: h = g * t ^ 2/2 = 10 * 3 ^ 2/2 = 45 m.
Answer: The height of the building is 45 m.
