The forces on an aircraft flying at altitude are shown in the picture. An F35 fighter jet has a mass m = 14,000 kg and its engines are capable of a maximum thrust TMAX = 190,000 N. (a) At a cruising speed of 250 m/s the air drag is 40,000 N. What is the maximum forward acceleration that the F35 can achieve? (b) This aircraft’s wings have a total cross-sectional area of 43 m2. What is the pressure difference between the upper and lower side of the wings required for the aircraft to fly at constant altitude? (Hint: the vertical forces must cancel.)

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
