Answer to Question #135169 in Physics for jordan

Question

An airplane travels 209 Km on a straight course at an angle of 40 degrees, EAST OF NORTH. it then changes its course by moving 100 Km NORTH before reaching its destination. Determine the RESULTANT DISPLACEMENT of the airplane.

PLEASE FOLLOW THESE FORMAT FOR YOUR ANSWER. BUT YOU HAVE TO GET A PIECE OF PAPER TO ANSWER THIS PROBLEM.

Answer 1

As we see, the resultant displacement can be found by simple math:

$$D_y=100+209\text{ cos}40°=260\text{ km}.\\ D_x=209\text{ sin}40°=134\text{ km}.\\ D=292\text{ km}.$$
