An airplane flies 800 km east and 600 km north. What is the total displacement (with approximate direction)? What is the total distance traveled?

Total displacement is found using pythagorean theorem

d = sqrt( 800^2 + 600^2) = 1000 km

 

Direction is given by Tan = opp/adj    =     600/800            arctan (600/800) = 36 .9 degrees

You're welcome....good luck with Physics !     cheeky

For displacement, I was told to subtract the final position - the initial position. 

 

Doing that I got

 

-200km North

Not sure who told you that, but it is incorrect.....sorry cheeky

 

 

Hypothetical example:   IF you move 800 east  and then   400 west THEN your displacement would be 800 - 400 = 400       This ONLY works with displacements along a LINE.
