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.)

- A 4.5-kg object is dropped vertically (with zero horizontal speed) from a tall building with an initial velocity 6.6 m/s (positive is downwards). Due to aerodynamic drag, the object's downward acceleration is given by a = g -(k/m)*v2 where g is acceleration due to gravity (use 9.81 m/s?) and k = 0.19 kg/m is a coefficient related to aerodynamic drag. Determine the distance the object will fall to reach 90% of its terminal velocity. Assume the building is tall enough so that the object can reach that speed and that g is constant. Hints: • First, calculate the object's terminal velocity.
