The speed of the aircraft, moving at a speed of 50 m / s, increased for 5 s. At the same time, the plane moved 300m. How fast was the plane moving at the end of this section of the route?
To find the speed of the aircraft at the end of the track section under consideration, we use the formula: S = (V1 + V2) * t / 2, whence we express: V2 = 2S / t – V1.
The values of the variables: S – the length of the track section under consideration (S = 300 m); t is the duration of the aircraft speed increase (t = 5 s); V1 – initial speed (V1 = 50 m / s).
Calculation: V2 = 2S / t – V1 = 2 * 300/5 – 50 = 70 m / s.
Answer: At the end of the considered section of the route, the plane reached a speed of 70 m / s.
