An airplane is flying with an air velocity of 850 km/h at 34 degrees n of e. The wind is blowing at 100 km/h at 20 degrees s of e. Find the ground velocity of the airplane.
break the vectors into components. On each components, the resultant is airveloctiy+groundspeed.
I will do the N component.
Resultant=850sin34 + 100sin(-34). N component.
