A jet aircraft with mass of 631,405.4 kilograms is flying straight downward. At an instant the plane's engine is producing an downward thrust (force) of 3,329,281.8 Newtons and air resistance is exerting a force of 714,785.5 Newtons upward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "down" as positive.

Answer #1

1. Net force on the plane: - Fret = Thrust + Weight - Air resistance - mxa. = 3329281.8+ mg - 716785.5 631405.4 a=3329281.8 +
