Question

Bx = -1.33 m and By = 2.81 m.
Find the direction of the vector.

Answer 1

115.33

Step-by-step explanation:

Answer 2

Step-by-step explanation:

The vector in unit vector notation is:

B = (-1.33m)i + (2.81m)j

To find the direction relative to the x-axis. Do inverse tangent of opposite/adjacent

`tan^-^1=|(2.81)/(1.33)| = 2.11\\180-2.11=177.89`

This is relative to the positive x-axis

2.11 would be the correct answer if relative to the negative x axis
