Chapter 3, Problem 75GP
A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 12 m/s. A wise elder duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 16 m/s relative to the air, in what direction should they head in order to move directly south?

If the ducks can fly at 16 m/s relative to the air, in what direction should they head in order to move directly south?
A flock of ducks is trying to migrate south for the winter, but they keep being blown off course by a wind blowing from the west at 6.0 m/s. A wise duck finally realizes that the solution is to fly at an angle to the wind. If the ducks can fly at 8.0 m/s relative to the air, what direction should they head in order to move directly south? What will be their speed, relative to the ground?
A plane headed due south is traveling with an airspeed of 200 miles per hour. The wind currents are moving with constant speed in the direction 330°. If the ground speed of the plane is 100 miles per hour, what is its true course?

- An airplane flies due north through the air at a speed of 75 m/s in a wind from the west at 10 m/s. What is the ground speed of the plane and what direction will it go?arrow_forwardCanada geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. One goose is flying at 100 km/h relative to the air but a 30 km/h wind is blowing from west to east. At what angle relative to the north-south direction should this bird head to travel directly southward relative to the ground? How long will it take the goose to cover a ground distance of 450 km from north to south? (Note: Even on cloudy nights, many birds can navigate using the earth's magnetic field to fix the north-south direction.)arrow_forwardA plane is capable of flying 180 km/h in still air. The pilot, takes off from an airfield and heads due north according to the plane's compass. After 30 minutes of flight time, Captain notices that, due to the wind, the plane has actually travelled 80 km at an angle of N5°E. (You may assume that the wind velocity remains constant through the entire question.) a) What is the wind velocity? b) In what direction should the pilot have headed to reach the intended destination (due North) ○ ) If the original destination was 300km due N from her original starting point, what heading should Captain take now to adjust for the oversight and reach her destination? d) How much time did Captain waste because of this oversight?arrow_forward
- You are taking flying lessons from an experienced pilot. You and the pilot are up in the plane, with you in the pilot seat. The control tower radios the plane, saying that, while you have been airborne, a 25-mi/h crosswind has arisen, with the direction of the wind perpendicular to the runway on which you plan to land. The pilot tells you that your normal airspeed as you land will be 80 mi/h relative to the ground. This speed is relative to the air, in the direction in which the nose of the airplane points. He asks you todetermine the angle at which the aircraft must be “crabbed,” that is, the angle between the centerline of the aircraft and the centerline of the runway that will allow the airplane’s velocity relative to the ground to be parallel to the runway.arrow_forwardAfter flying for 15 min in a wind blowing 42 km/h at an angle of 25° south of east, an airplane pilot is over a town that is 48 km due north of the starting point.
