Nope, use Pythagoras's theorem to calculate the magnitude of the total displacement of the plane.kara said:A plane flies 483 km east from city A to city B in 45.0 min and then 966 kim south from city B to city C in 1.50 h. For the total trip, what are the magnitude and direction of the plane's displacement, the magnitude and direction of its average velocity, and its average speed?
Would this be correct:
I calculated r the distance between points A and C by r = (483 km) + (- 966 km) to get - 483 km
So the planes magnitude was 483 km in the negative direction, or south east. Is this correct?
Exactly. By the way, the 'arrow' points from A to C.kara said:ok.. so i used pythagorean theorem and got this:
r = 1080.020833 which i'll round to 1080 for 4 sig figs.
Now finding r gave the the magnitude would i use the tan formula to find direction???
Yes, you're right. Again, look at the vector addition rule I linked somewhere above, it should make everything clear.kara said:...
If i draw the diagram on the cartesian plane i get the final location of the plane to be in the -y +x coordinate, so it would be in the south east direction??? am i right???
