an airplane is cruising along in a horizontal level flight at a constant velocity, heading due west. (a) If the weight of the plane is 2.6 x 10^4 N what is the net force on the plane? (b) with what force does the air push upward on the plane? (c) Is the plane in equilibrium? If so, what kind of equilibrium? I got answers but i am not too sure on them so if someone could check that would help. For (a) i got 2.6 x 10^4 west. for (b) i got gravity 9.8 N/kg for (c) i got dynamic equilibrium. Any help with this matter would be greatly appreciated!!!
