If an aircraft is flying in constant sustained flight at 35,000 ft above sea level, at 500 miles per hour, the planes lift force is 675,000 pounds, and a wing area of 4,605 square feet. The plane is flying on Tuesday in the summer, the plane is almost at full passenger capacity, the pilot has brown hair, and one of the flight attendants appears to be in a bad mood.
What is the plane's weight?
What is the drag force?
And Why?
Ok sorry about the question but you would use Newton's 3rd Law of Physics:
Third law: When two bodies interact by exerting force on each other, these action and reaction forces are equal in magnitude, but opposite in direction.
Which means as Three60 said: I would imagine that the drag force is exactly equal to the thrust since speed is constant, and the weight balances the lift since height is constant.
What you said here is exactly correct.
Please go ahead Three60 with a More General Knowledge Question
