The helicopter flies in a horizontal direction at a speed of 40 m / s. A load fell out of it and touched the ground after 4 s. How high is the helicopter flying? Neglect air resistance

To find the altitude at which the specified helicopter should fly, we use the formula: S = h = a * t ^ 2/2 = g * t ^ 2/2.

Data: g – acceleration due to gravity (g ≈ 9.8 m / s2); t is the duration of the fall of the dropped load (t = 4 s).

Let’s perform the calculation: h = g * t ^ 2/2 = 9.8 * 4 ^ 2/2 = 78.4 m.

Answer: The altitude at which the indicated helicopter flies is 78.4 m.
