The aircraft, accelerating before takeoff, moved uniformly accelerated for a certain period of time.

The aircraft, accelerating before takeoff, moved uniformly accelerated for a certain period of time. What was the acceleration of the aircraft in this case, if in 20 s its speed increased from 20 m / s to 60 m / s?

Task data: t (specified time interval during acceleration) = 20 s; V1 (initial speed at the moment of acceleration) = 20 m / s; V2 (final speed at the moment of acceleration) = 60 m / s.

The acceleration with which the plane moved during acceleration can be calculated by the formula: a = (V – V0) / t.

Let’s calculate: a = (60 – 20) / 20 = 2 m / s2.

Answer: The aircraft acceleration during acceleration was 2 m / s2.
