An airplane flies due north at 200 km/h, and the wind blows in a direction N30°E at 40 km/h. Find the coordinates for the vector representing the resultant for the airplane with the wind factored in, and the resultant airspeed. Show calculation and diagram.

this allows people to make the best decision or pursue the best option. when alternatives are weighed using their advantages and disadvantages, the option whose disadvantages outweigh the advantages (based on a qualitative or quantitative analysis) are shunned while those whose advantages outweigh their disadvantages are pursued.  

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
