Question 2: An airplane is gliding in a direction 10 degrees downward from the horizontal. Three forces act upon it: its weight of 10,000N; the lift, perpendicular to the direction of motion; and the drag of air friction, opposite to the direction of motion. Assume the plane moves with constant speed and compute the value of the lift.
