Question

Vector B has components Bx = 6.18 and By = 4.43. Find the magnitude and direction counter clockwise from the positive x-axis.

Answer 1

Step-by-step explanation:

The formula for the magnitude of this resultant vector, which is in Q1, btw, is:

`B_(mag)=√(6.18^2+4.43^2)` which gives us, to 3 sig fig's:

7.60 m. Since the resultant vector is in Q1, we don't need to add anything to the angle once we find it to 3 sig fig:

`tan^(-1)((4.43)/(6.18))` gives us an angle of 35.6 degrees
