Physics vectors and resultants.?
Amit flies due east from san fran to DC a displacemenet of 5600km he then flies from DC ro boston a displacement of 900km at an angle of 55 degress east of north. What is the total displacement?

it is simply an addition of vectors
from san fran to dc, let it vector A
from dc to boston, let vector B
the total displacement, let vector C
B=(900*sin 55)i +(900*cos 55)j
i and j are unit vectors
C = A+B
C=5600i +737.24i + 516.22j
C= 6337.24i +516.22j
to solve for the magnitude of vector C
/C/ = sqrt(6337.24^2 +516.22^2)
= 6358.23 km
