September 30, 2021 | education

| These tasks: t (the duration of the aircraft take-off run) = 25 s; a (acceleration during takeoff) = 3 m / s2; V0 (initial speed of a given aircraft) = 0 m / s.

The takeoff speed of a given aircraft is calculated by the formula: V = V0 + a * t.

Let’s make a calculation: V = 0 + 3 * 25 = 75 m / s.

Answer: The given aircraft had a takeoff speed of 75 m / s.
