An airplane weighing 70 tons, moving from rest, picks up speed of 360 km / h during acceleration. What is the impulse of force acting on the plane?
To calculate the momentum of the force acting on a given aircraft, we apply the formula: I = F * Δt = m * V – m * V0.
The values of the variables: m is the mass of the aircraft (m = 70 t = 70 * 10 ^ 3 kg); V is the speed gained during acceleration (V = 360 km / h = 100 m / s); V0 – initial speed (V0 = 0 m / s).
Let’s perform the calculation: I = 70 * 10 ^ 3 * 100 – 70 * 10 ^ 3 * 0 = 7 * 10 ^ 6 kg * m / s.
Answer: The impulse of the force acting on the given aircraft was 7 * 10 ^ 6 kg * m / s.
