As an airplane (mass 620 kg) increases its speed, air resistance increases.
a) What force must the engines exert in order to accelerate the plane at a rate of 2.4 m/s2 if the airplane is flying at a speed of 20 m/s, with the air resistance at 300N?
b) What force must the engines exert if the plane is flying at a constant speed of 50 m/s, with the air resistance at 1.8 kN?
