1. The problem statement, all variables and given/known data An airplane is heading due south at a speed of 500 km/h. If a wind begins blowing from the southwest at a speed of 100 km/h, calculate the velocity of the plane relative to the ground, and how far off course it will be after 10 min. if the pilot takes no corrective action. Answer: 435 km/h, 9.36 degrees east of south 2. Relevant equations x = hypotenuse * cos(45) x = 100 km/h * cos(45) y = hypotenuse * sin(45) Y = 100 km/h * sin(45) 3. The attempt at a solution First I drew a diagram with N, E, S, W labeled. I then drew a line going NE since the wind is coming from SW. Then using the same starting point as the wind I drew 500 km/h going south to represent the airplane. I now wrote in a 45 degree angle for the wind. From this point I made a right triangle for the wind. To find the x and y I used sin and cos to get the values y = 70.71 km/h and x = 70.71 km/h. Am I on the right track or no?
