The plane flies at a speed of 900 km / h. On the way of the plane was a bird weighing 2 kg. Determine the force of the bird’s impact on the aircraft if the impact duration is 0.001 s.

Task data: V (flight speed) = 900 km / h (in SI V = 250 m / s); m (bird weight) = 2 kg; Δt (duration of the bird hitting the aircraft) = 0.001 s.
To determine the force of impact of the considered bird on the aircraft, we use the equality: F * Δt = m * V and F = m * V / Δt.
Calculation: F = 2 * 250 / 0.001 = 500 * 10 ^ 3 N (500 kN).
Answer: The force of impact of the considered bird on the aircraft is 500 kN.
