Problem 81P

An airplane pilot sets a compass course due west and maintains an airspeed of 220 km/h. After flying for 0.500 h, she finds herself over a town 120 km west and 20 km south of her starting point. (a) Find the wind velocity (magnitude and direction). (b) If the wind velocity is 40 km/h due south, in what direction should the pilot set her course to travel due west? Use the same airspeed of 220 km/h.

Use the same airspeed of 220 km/h.

ANSWER:

Solution 81P

Step 1 :

In this question, we need to find the

Velocity of the wind along with the magnitude and direction

If  the velocity of wind is 40 km/h due to south, what direction should the set the course of the travel due to west using the same air speed of 220 km/h

Let us consider the data given

Airspeed of plain

distance travelled along west  

distance traveled along south
