Question

Use unit vectors to express the vector C? , where C? =3.00A? ?4.00B? .
Part E Find the direction of C? . 350.09   ? counterclockwise from +x-axis
#it told me 350.09 is wrong answer Part E Find the direction of C? . 350.09   ? counterclockwise from +x-axis
#it told me 350.09 is wrong answer 350.09   ? counterclockwise from +x-axis
#it told me 350.09 is wrong answer 350.09   ? counterclockwise from +x-axis
350.09 350.09   ? counterclockwise from +x-axis Write the vector in the figure (Tap image to zoom in terms of the unit vectors i circumflex and = 1.23 + 3.38

Explanation / Answer

Angle of vector from +x axis in clockwise direction = tan inverse (3.38/1023)

=69.99 Degree

So in conterclockwise it will be 360-69.99

=290.01 Degrees

You are getting an wrong answer because you may be confused with radian and Degre value. but this is correct. Cheers !
