With what acceleration did a jet plane with a mass of 50 tons move during takeoff if the thrust force of each of the two engines was 50 kN.
m = 50 t = 50,000 kg.
F1 = 50 kN = 50,000 N.
a -?
According to 2 Newton’s law, the acceleration of a body a is directly proportional to the force F, which acts on the body, and is inversely proportional to the mass of the body m: a = F / m.
Since the plane has 2 engines and the thrust force of one is equal to F1, the thrust force F = 2 * F1 acts on the plane.
The formula for jet aircraft acceleration will be: a = 2 * F1 / m.
a = 2 * 50,000 N / 50,000 kg = 2 m / s2.
Answer: during the takeoff run, the jet plane moves with acceleration a = 2 m / s2.
