SUMMARY
The discussion focuses on calculating an airplane's constant acceleration during takeoff, given that a passenger observes a pocket watch at an angle of θ = 14° for a duration of 13.3 seconds. The key equations utilized include Newton's second law, F = ma, and the analysis of force components acting on the pocket watch. The forces identified are tension (T) and weight (mg), with their respective horizontal and vertical components being T*sin(14°) and mg for tension, and 0 and mg for weight. The solution involves applying the sum of forces to determine the plane's acceleration and distance traveled on the runway.
