A commercial liner approaches an airport descending from the height of 3.00 km along a straight line at the angle of 20 below the horizontal with the speed of 450. mi/h. a) Find the horizontal and vertical components of the velocity of the airplane. b) On what height does the airplane appear 10.0 s after if it keeps the same velocity? A helicopter moves 50 km at 30 north of east, then it makes turn to west and moves 35 km. a) Sketch a diagram showing displacements for the both legs. b) Determine the magnitude and direction of the total displacement. c) What is the total distance traveled by the helicopter
